Objective
To identify and represent patterns that describe nonlinear functions
nonlinear function
The relationship in the Solve It is an example of a nonlinear function. A nonlinear function is a function whose graph is not a line or part of a line.
Essential Understanding Just like linear functions, nonlinear functions can be represented using words, tables, equations, sets of ordered pairs, and graphs.
