2. Emma wants to compare some cell phone plans by graphing their cost per text message. Mobilama charges a flat rate of \$30 for unlimited texts. Celly-On-The-Go has no set-up charge, but it does charge \$0.10 per text. Ringit Wireless only charges \$0.05 per text, but it has an account charge of \$15.

Explain to Emma how she can graph these cell phone plans and, describe what key features of the graphs she should consider when making a decision.

3. Francisco and Ryan are stuck simplifying radical expressions. Francisco has simplified to . Ryan has simplified to . Using full sentences, describe how to fully simplify Francisco and Ryan's expressions. Describe if Francisco and Ryan started with equivalent expressions or if they started with expressions that are not equal.

4.When solving a radical equation, Beth and Kelly came to two different conclusions. Beth found a solution, while Kelly's solution did not work in the equation.

Create and justify two situations: one situation where Beth is correct and a separate situation where Kelly is correct.

5.Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing, and the end behavior when the following changes are made. Make sure to account for even and odd functions.
