y=f%28x%29
recall: y actually means f%28x%29
I find it helps sometimes to think of a function as a machine, one where you give a number as input to the machine and receive a number as the output. The name of the function is f, the input is x, and the output is read " f of x". The output is f%28x%29 sometimes given an additional name y by y=f%28x%29.
The domain of the function y=f%28x%29 is the set of values of x for which a corresponding value of y exists.
The range of the function y=f%28x%29 is the set of values of y which correspond to the values of x in the domain.
