The document provides information and examples about graphing functions using calculators: 1) It defines a complete graph and lists the elements it must show, such as turning points and intercepts. 2) It instructs the reader to familiarize themselves with appendix A of the textbook to learn how to adjust windows and use table and trace features on calculators. 3) It provides examples of completing graphs of functions and using calculators to evaluate functions and fill in tables.

1. Section 1.2Graphs of Functions

2. Complete Graph A complete graph is defined in the textbook as showing: Basic shape of the graph. Turning points and/or intercepts. Where the graph is headed.

3. Textbook Calculator Reference Refer Appendix A (pp. 654-655) to familiarize yourself with your calculator. You need to be able to, Adjust the window to see the part of the graph that is useful to you. Use the TABLE Ask feature. Use TRACE to evaluate the function.

4. Pg. 39 #24 Complete graph of 𝑦=−𝑥2+34𝑥−120. (A complete graph shows one turning point.) Scroll over the calculator image to view the Video menu.

5. Pg. 40 #26 Using a calculator to fill in the following table:

6. Pg. 40 #32 𝑓𝑥=100𝑥2−5𝑥 thousand units 𝑥=number of years after 2000 What is 𝑓10? 𝑓10=100102−5(10) =9950 How many units are produced in 2010? We need the output for the input 𝑥=10, which we have already found in part(a) to be 9950. Remember that the thousands are implied, so 9950 X 1000=9,950,000 units are produced in 2010.
