Functions
We are learning to model functions as tables,
graphs and equations (rules).

“NON-LINEAR”
With your team brainstorm characteristics of graphs,
tables, and equations for both linear and non-linear
functions.

Group Practice

With your group identify the representations (table
and equation) for the functions and identify each as
either “linear” or “non-linear.”


Be sure to provide proof in complete sentences.
Then explain in complete sentences what it means
for a function to be linear. Next explain what it
means for a function to be non-linear.

Demonstrate your reasoning in more than one way.
