You can do this by inspection of the graph, or using the graphing calculator techniques.  For the TI84, use 2nd, F4(CALC).  I have a 24 page explanation of the TI84 that is available FREE on my website.  To find my website, use the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com.  Click on the link at the bottom of the page, which takes you to my Homepage.  Near the bottom of my Homepage is a link \"Calculator Links and Handouts\" that will take you to the pages that you can print yourself.
