A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Is it ever possible for the domain and range in a function to have different numbers of entries for example 3 domain entries to 5 range entries or 2 range entries to 7 domain entries?

Yes. The range can have fewer number of entries.As an extreme case, consider f(x) = 3, where x is a Real number.The domain is all Real numbers - infinitely many of them, while the range is one value: 3.A function can contain one-to-one or many-to-one relationships but one-to-many relationships are not permitted. As a result, the cardinality of the range cannot be bigger than the cardinality of the domain.


What is is a domain?

In algebra, a function, is a mapping (or a relationship) between two sets: the domain and the codomain (or range). To each element of the domain, a function assigns one element of the range.


What is the domain and range of y equals the square root of four minus x squared?

The domain and the range depends on the context. For example, the domain and the range can be the whole of the complex field. Or I could define the domain as {-2, 1, 5} and then the range would be {0, 3, -21}. When either one of the range and domain is defined, the other is implied.


Is it true in a relation for each element of the domain there is only one corresponding element in the range?

Is it true that in a relation for each element of the domain there is only one corresponding element in the range


What is the correspondence of the domain and range of a linear function?

It is a bijection [one-to-one and onto].


How does one find the range of a radical function?

You need to know the domain in order to find the range.


Can the members of the domain be in the members of the range and be a function?

Yes, the domain must correspond to only one member of the range in order to be a function in a member of the domain goes to more than one member of the range it then is a relation and not a function A function is a relation but a relation isnt always a function


What is the example of the range and domain in a function?

A function is a mapping from one set to another. It may be many-to-one or one-to-one. The first of these sets is the domain and the second set is the range. Thus, for each value x in the domain, the function allocates the value f(x) which is a value in the range. For example, if the function is f(x) = x^2 and the domain is the integers in the interval [-2, 2], then the range is the set [0, 1, 4].


How do you find the domain?

The domain of a function, is the range of input values which will give you a real answer.For example the domain of x+1 would be all real numbers as any number plus 1 will be another real numberThe domain of x0.5 would be all positive numbers as the answer to square root of a negative number is not realNote:x0.5 means the square root of x* * * * *Not quite. A function is a one-to-one or many-to-one mapping from a set S to a set T (which need not be a different set). A function can be one whose domain is all the cars parked in a street and the range is the second character of their registration number.A mathematical function can have the complex field as its domain and range, so a real answer is not a necessary requirement for a function.


Describe what it means for a function to be one to one?

It is the function for which all the elements of the range of the function corresponds to exactly one element of the domain.


A relation in which each element of the domain is paired with exactly one element of the range?

A relation where each element of the domain is paired with only one element of the range is a one to one function. A one to one function may also be an onto function if all elements of the range are paired.


Which relation are function relation?

A relation is a mapping between two sets, a domain and a range. A function is a relationship which allocates, to each element of the domain, exactly one element of the range although several elements of the domain may be mapped to the same element in the range.


What is the function of relation domain and range in mathematics?

A relation is a mapping from elements of one set, called the domain, to elements of another set, called the range. The function of the three terms: relation, domain and range, is to define the parameters of a mapping which may or may not be a function.


Is the relation a function Why or why not (3 1) (3 0) (3 4) (3 8)?

No it is not. The number 3, in the domain, gets mapped to more than one number in the range.


How does one look up domain names?

By using Google, you can search for domain names. Also by visiting Domain websites such as GoDaddy, you can find a list of a range of different domain names.


What is the price range for Domain Monster services?

Domain Monster is a UK website one can go to, if one wants to register a domain name. Domain Monster's services cost between 2.69 Euros and 17.99 Euros.


A relation in which element of the domain is paired with exactly one element of the range?

Function


What is function and relation?

All functions are relations with the condition that each element of the domain is paired with only one element of the range. A relation is any pairing of numbers from the domain to the range.


What is the domain and range for y equals x squared minus 4?

You can define the domain as anything you like and that will determine the range. Or, you can define the range as anything you like and that will determine the domain. For example: domain = {1, 2, 3, 4, ... } then range = {-3, 0, 5, 12, ... } or range = {1, 2, 3, 4, ... } then domain = {sqrt(5), sqrt(6), sqrt(7), sqrt(8), ...}. There is, of course, no need to restrict either set to integers but then it was easier to work out one set from the other.


Number represented by a whole number and fraction?

A number represented by a whole number and a fraction (for example, 1 1/2 - one and a half) is called a mixed number.


Is y equals negative one a function why or why not?

It depends on what the domain and the range are. If the range is the positive integers, then the mapping is not even defined.


How would you use domain and range to determine whether a relation is a function?

Each element in the domain must be mapped to one and only one element in the range. If that condition is satisfied then the mapping (or relationship) is a function. Different elements in the domain can be mapped to the same element in the range. Some elements in the range may not have any elements from the domain mapped to them. These do not matter for the mapping to be a function. They do matter in terms of the function having an inverse, but that is an entirely different matter. As an illustration, consider the mapping from the domain [-10, 10] to the range [-10, 100] with the mapping defined by y = x2.


How do you find range?

To find range, you look at the points. Say the points are: (1,2) (4,8) (5,7) and (2.6). Then, your Range would be 1,4,5, and 2. You can see that Range is just another word for the x-coordinate. Also, if you have more than one of the same number in the Range or Domain; you only have to write it once. (Domain would be 2,8,7, and 6. It is also just another word for the y-coordinate.)


What is meant by the domain and range of a relation?

A relationship is a way of associating members of one set to members of another set (the two sets could be the same). The first of these sets is the domain and the second is the range.


What is 4 one half into a whole number?

Four and one-half cannot be represented by a whole number. It can be represented by 4.5 or the improper fraction 9/2
