CHAPTER 5
Inverses and Radical Functions
THEN
You simplified polynomial
expressions.
NOW
You will:
Find compositions and inverses of
functions.
Graph and analyze square root
functions and inequalities.
Simplify and solve equations
involving roots, radicals, and
rational exponents.
WHY
FINANCES
Connecting finances
to mathematics is a skill that, once
mastered, you will use your entire life.
Learning to manage your finances
includes anticipating costs, such as
college, and preparing for them.
Use the Mathematical Practices to
complete the activity.
1. Using Tools
Use the Internet
to find the annual tuition for the
college you plan to attend. Then,
use the Internet to find the tuition
costs over the last four years.
2. Applying Math
Calculate the
average annual rate of increase in
tuition. Then, create a Line Graph
that plots the tuition costs over
the last four years and projects the
tuition costs through the end of
your four years in college.
