Understand and compare functions (8.F.A.1, 8.F.A.2)

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. Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

Lessons

    In this lesson you will learn how to identify a function by investigating a real-world example.

  • Identify function properties

    In this lesson you will learn how to identify function properties by examining the input and output of real world examples.
