Hello! Comparing Functions is one of the power standards for 8th grade math. This 5 part resource includes PARCC aligned problems that are appropriately scaffolded. There is a resource summary as well as implementation suggestions. An answer key is provided. Enjoy!

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.
Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change.
