7.1 Absolute Value
In order to complete this section you will need to graph linear and quadratic equations. Please watch the review graphing video and then return to this site.
Absolute value is defined as the distance from zero a point is on the number line. Because it represents a distance, absolute value is always positive. Please watch the absolute value video and complete the work below.
Please do page 363 #1, 4, 6 and graph the four equations provided to you by your teacher on graph paper.

7.2 Absolute Value Functions
This section concentrates on the graphs of absolute value functions. Please watch the absolute value intercepts video which explains how to find the x- and y-intercepts of an absolute value function and then return to this site.
When graphing an absolute value function, it is easiest to graph the related non-absolute value function and then reflect the part of the graph below the x-axis. Please watch the graphing absolute value video now and then work on the questions below.
Please do page 375 #2-4 (sketch these), 5b, 6be, 7b, 8ae, 12, 13
