ABSOLUTE VALUE FUNCTIONS Graphing And Analysis (Page 1 of 5)

Let's graph the absolute value function f(x) = abs(2x+7)-3. Enter this function as Y1, then try a standard window. The absolute value function is located in the MATH NUM submenu.

 Y= key. (Clear any previous functions)

 MATH key. [NUM] 1: menu selection. 2 X,T,theta,n key. Plus key. 7 Right parenthesis key.
 Minus key. 3

 ZOOM key. 6: menu selection.

A comprehensive graph of an absolute value function should show all intercepts and the minimum or maximum point (the "point" of the "v"). For this function, the standard window provides a good viewing rectangle.
