Reference To A Function

Recall from algebra that a function f is a rule that assigns to each real number x in its domain a unique
real number f(x) in its range. Strictly speaking, f is the function and f(x) is the value of the function f at
x. However, we sometimes loosely refer to f(x), or y if y = f(x), as the function.
