MAAC.D.36

MAAC.D.36: understand that a function from one set (the input, called the domain) to another set (the output, called the range) assigns to each element of the domain exactly one element of the range [i.e., if f is a function, x is the input (an element of the domain), and f(x) is the corresponding output (an element of the range); the graph of the function is the set of ordered pairs consisting of an input and the corresponding output]
