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 πΉ is an element of its domain, then π§(πΉ) denotes the output of π§ corresponding to the input πΉ. The graph of π§ is the graph of the equation πΊ = π§(πΉ).
