The allowable values of x are called the "domain", and the resultant set of possible y values are called the "range".
Its called a varible.
The Input or X values are called the Domain.
the domains
Domain is what you can plug into the function (possible x values for y=f(x) type functions) and range is the possible values you can get out (possible y values).
y = x This is a line and a function. Function values are y values.
"Domain" means for what numbers the function is defined (the "input" to the function). For example, "x + 3" is defined for any value of "x", whereas "square root of x" is defined for non-negative "x". "Range" refers to the corresponding values calculated by the function - the "output" of the function. If you write a function as y = (some function of x), for example y = square root of x, then the domain is all possible values that "x" can have, whereas the range is all the possible values that "y" can have.
In algebra, the domain consists of all possible values for the x variable that could make the function work. The range is all of the possible values of the function, using each number in the domain.
A function, f, is usually a mapping from a set of input values. This set, whose elements are often denoted by x, is called the domain.A function, f, is usually a mapping from a set of input values.

These are usually the domain of the function.
Range: The range is the set of all possible output values (usually y), which result from using the function formula. Domain: The domain of a function is the set of all possible input values (usually x), which allows the function formula to work.
X > 9
They can be any values in the domain of the function.
