Compare Functions

Examples, solutions, videos, and lessons to help Grade 8 students learn how to 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.

Common Core: 8.F.2

Suggested Learning Targets

• I can identify functions algebraically including slope and y intercept
• I can identify functions using graphs.
• I can identify functions using tables.
• I can identify functions using verbal descriptions.
