```Lesson 3:
Patterns and Nonlinear Functions
Objective: SWBAT--identify and represent patterns that describe
nonlinear functions
Warm-Up
I. Vocabulary
1. Nonlinear function
II. Classifying as Linear or Nonlinear
The number of centimeters is a function of the number of
inches as shown in the table. Is the function linear or
nonlinear?
Linear
 The table shows the number of calls made in a phone tree
during each level. Identify the pattern to complete the table.
How can you represent the relationship using words, an
equation, and a graph?


The number of calls
y = 2x
made at a level is
(4, 16), (5,32)equal to 2 raised to
the level number.
 The ordered pairs (1,1), (2,8), (3,27), (4,64) and (5,125)
