domain
The set of values of the independent variable, x, for which the function f(x) is defined; the set of values of the dependent variable is called the range. For example, let the function by y = x2, with x restricted to 0, 1, 2, 3, -3, and -5. Then y takes the values 0, 1, 4, 9, and 25 respectively. The domain is [0, 1, 2, 3, -3, -5] and the range is [0, 1, 4, 9, 25].
