Going Beyond

 

Part A

 

In this lesson you learned several strategies for solving quadratic inequalities. You can extend these strategies to the solution of polynomial inequalities.
           

The following graph represents the cubic function f(x) = 0.08(x + 5)(x + 2)(x – 7).

 

 

Apply at least two of the strategies you used in this lesson to solve the inequality 0.08(x + 5)(x + 2)(x − 7) ≤ 0.

Part B: Calculate Your Carbon Footprint

 

You can determine your impact on the environment by calculating your own carbon footprint. Search the Internet for “carbon footprint calculator.” Find a calculator that allows you to input information about your lifestyle and environmental practices.
