# Standards Addressed

- Understand that a function is a rule that assigns to each input exactly one output. The graph of a
function is the set of ordered pairs consisting of an input and the corresponding output. (Common
Core Math 8.F.1.)
- Compare properties of two functions each represented in a different way—algebraically,
graphically, numerically in tables, or by verbal descriptions. (Common Core Math 8.F.2)
- Construct a function to model a linear relationship between two quantities. Determine the rate of
change and initial value of the function from a description of a relationship or from two (x, y)
values, including reading these from a table or from a graph. Interpret the rate of change and
initial value of a linear function in terms of the situation it models, and in terms of its graph or a
table of values. (Common Core Math 8.F.4)
- Describe qualitatively the functional relationship between two quantities by analyzing a graph
