# Functions

Understand that a function has exactly one output for each input. The graph of the function is the set of ordered pairs consisting of an input and corresponding output. Compare properties of two functions represented in different way. Construct a function to model a linear relationship between two quantities. Describe the functional relationship between two quantities by analyzing a graph. Sketch the graph that exhibits qualitative features of a function.
