4.3 Patterns and Nonlinear
Functions
I can identify and represent patterns
that describe nonlinear functions.
y=x
y = x2 – 7
y = x3 – 5
y = |x|
y = -2x + 3
Representing Patterns
• Draw a table showing the number of blocks on
one edge to the total number of blocks.
• Is this relationship linear or nonlinear?
• This is called cubic.
Writing a Rule
• The ordered pairs (1,2), (2,4) , (3,8), (4, 16),
and (5,32) represent a function. What is the
rule?
• Make a table to help.
• 𝑦 = 2𝑥
