NOTES: Linear vs. Non-Linear Functions Date
Today’s Objectives
 Identify linear functions by looking at a table, graph or equation.
 Identify nonlinear functions by looking at a table, graph or equation.
We already know that linear functions are
.
This is because the
between any two data points is
a
A
.
function is a function whose rate of change is
. That means that
their graphs are not
.
Examples:
Determine whether each table represents linear or non-linear functions. Explain.
