A function may be defined over only certain values. That is, it may have only a certain set of values that can serve as input. For example, in elementary mathematics, the principal square root is only defined for non-negative real numbers. This is the "area" over which the function is valid and so it is called the domain.
The mathematical term for the set of output values is actually the co-domain, but many people refer to it as the range.
What else can I help you with?
How do you describe the domain and range of a function?
The domain is the set of values of the input while the range is the set of output values.
What are domain and range in math?
The domain of a function is a set of input values that make the function work, usually symbolized by an 'X'. The range. The range is the output values that result from using the function, usually symbolized by a 'Y'.
Does every function have a domain and range?
yes, bcoz evey function gives some output for input. Except constant function.
What is the domain of a discrete function?
The domain is the possible values that can be input into the function and produce a real number output.
How do you identify the range of a function in math?
It can be quite hard. First determine the domain. Then, for every input value from the domain, calculate the output value. The set of all these output values is the range. For simple functions you will not need to find every output value. For monotonic continuous functions the end points of the domain will determine the endpoints of the range. [Monotonic means never decreasing or never increasing]. For non-monotonic functions, for example a quadratic or polynomial of higher order, you may need to find the turning points.
How do you describe the domain and range of a function?
The domain is the set of values of the input while the range is the set of output values.
What is the range of the sine function?
The domain (input) is all possible angles. The range (output) is -1 to +1.
What is the domain and range of the sine function y is equal to 2 sin x?
Domain (input or 'x' values): -∞ < x < ∞.Range (output or 'y' values): -2 ≤ y ≤ 2.
What are domain and range in math?
The domain of a function is a set of input values that make the function work, usually symbolized by an 'X'. The range. The range is the output values that result from using the function, usually symbolized by a 'Y'.
What is math domin?
If you use an input output table, domain is the input.
How do you find the range for a function?
The range of a function is the set of all of the possible values that it can take on as an output value. You find the range by inspecting the function and seeing first what the domain is, and then what the range would be for that domain. The domain, then, is the set of all of the possible values that it can take on as an input value.
Is domain the input or output?
The imput or x value
What is meant by the term domain and range in maths?
Quite simply, the domain is the input and the range is the output of a function. If your using a typical X-Y axis graph, it may be useful to view the X axis as where the domain lies. The Y axis is where the range lies. Y= f(x) or Range = f(domain)
Does every function have a domain and range?
yes, bcoz evey function gives some output for input. Except constant function.
What is function and domain and range and Derivatives?
A function is a mapping or relationship from a set of inputs to a set of outputs such that for each input there is at most one output. The set of inputs is the domain. The set of outputs is the codomain or range. Derivatives are a characteristic of continuous functions. The derivative of a function at any point measures the rate of change in the output for very tiny changes in input, measured at that point.
State the domain and range for the following functions?
The domain is the set of all input values, the range is the set of all output values. It is not possible to be more specific when you have not included any details of the functions.
What is the domain of a discrete function?
The domain is the possible values that can be input into the function and produce a real number output.
