Question

What is the range of the function

Answer 1

Answer:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. In plain English, the definition means: The range is the resulting y-values we get after substituting all the possible x-values.

Answer 2

Answer:

The set of all output values of a function. It goes: Domain → function → range. Example: when the function f(x) = x2 is given the values x = {1,2,3,...} then the range is {1,4,9,...}
