Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If π is a function and π₯ is an element of its domain, then π(π₯) denotes the output of π corresponding to the input π₯. The graph of π is the graph of the equation π¦ = π(π₯).
