What else can I help you with?
Is it ever possible for the domain and range to have different numbers of entries what happens when this is the case?
Yes. Typical example: y = x2. To avoid comparing infinite sets, restrict the function to integers between -3 and +3. Domain = -3, -2 , ... , 2 , 3. So |Domain| = 7 Range = 0, 1, 4, 9 so |Range| = 4 You have a function that is many-to-one. One consequence is that, without redefining its domain, the function cannot have an inverse.
What is the definition fro sequence in math?
A sequence is a function with domain a set of successive integers
What are the advantages in using a rule for a function rather than listing function values in a table?
If the domain is infinite, it is not possible to list the function.
What is the number of non-square numbers between 2 consecutive numbers?
There is no such thing as consecutive numbers because numbers are infinitely dense. Between any two numbers there is another and so there is no such thing as a "next" number.There are no integers (square or non-square) between any two consecutive integers. There are infinitely many numbers between any two consecutive integers and, if the integers are non-negative, every one of these will be a square of some number so the answer is none. If the integers are negative then the infinitely many numbers will have a square root in the complex field but not in real numbers. In this case the answer is either none or infinitely many, depending on the domain.
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.
What is the domain of a sine function?
It is infinite, in both directions. But it can be restricted to a smaller interval.

What is the range on a line graph?
The answer will depend on the nature of the line graph.The range is often restricted when the domain is restricted. In that case, the range is the maximum value attained by the graph minus the minimum value. However, many algebraic graphs are defined from an infinite domain to an infinite range. Any polynomial function of power >1, for example, has an infinite range.The answer will depend on the nature of the line graph.The range is often restricted when the domain is restricted.

What advantages can you see of having a function rule instead of a table of values?
A table of values is no use if the domain is infinite.
If a system has an infinite number of solutions does it follow that any ordered pair is a solution?
No, this is not necessarily the case. A function can have an infinite range of solutions but not an infinite domain. This means that not every ordered pair would be a solution.

What are non-example of domain?
Non-examples of a domain include sets that do not meet the criteria for being a domain in a specific context. For instance, in mathematics, the set of all real numbers cannot be a domain for a function that is only defined for positive numbers. Similarly, if a function is defined only for integers, then any set containing non-integer values would not qualify as its domain.
Is the normal distribution infinite?
The domain of the normal distribution is infinite.
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].
