Introduction to College Algebra

Summer Assignment

You have enrolled in Introduction to College Algebra for the next school year. Show ALL of your work on this

paper and write your final answer(s) on the blank provided. Leave simplified, exact answers (improper

fractions, simplified radicals, etc). All work must be shown; just answers will receive a zero. When graphing,

be sure to number both axes, use a ruler, and plot at least 3 points. This assignment is due on the first day of

class next year. There will be a test on the topics during the first week of school. No assignments will be

accepted late!

A TI-83, TI-83+, or TI-84+ graphing calculator is mandatory for success in this class (and all other math

courses until you graduate college). If you do not already have one, and plan to purchase one over the summer;

please save the TI Reward Points. Staple the Reward Points to this sheet so you do not lose it. Thank you!
