The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0.

All these exercises and videos are teaching you how to find the domain using a function rule or a graph. Is there a way to do this for the range?

Determine the domain of a function according to the algebraic limitations of that function.
