The graph of y=sin(x) is like a wave that forever oscillates between -1 and 1, in a shape that repeats itself every 2π units. Specifically, this means that the domain of sin(x) is all real numbers, and the …

Checking whether a given set of points can represent a function. For the set to represent a function, each domain element must have one corresponding range element at most.

Learn what the inverse of a function is, and how to evaluate inverses of functions that are given in tables or graphs.
