Build an understanding 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 by recognizing that: • if f is a function and x is an element of its domain, then 𝑓(𝑥) denotes the output of f corresponding to the input x. • the graph of 𝑓 is the graph of the equation 𝑦 = 𝑓(𝑥).
