## Unit 8 Objectives

**I can ...
• **determine the domain and range of exponential functions of the form

*f*(

*x*) =

*abˣ*

**interpret the meaning of the values of**

•

•

*a*and

*b*in exponential functions of the form

*f*(

*x*) =

*abˣ*in real-world problems.

**•**write exponential functions in the form

*f(x)*=

*abˣ*(where

*b*is a rational number) to describe problems arising from mathematical and real-world situations, including growth and decay.

**•**graph exponential functions that model growth and decay and identify key features, including

*y*-intercept and asymptote, in mathematical and real-world problems.

**•**write, using technology, exponential functions that provide a reasonable fit to data and make predictions for real-world problems.
