### Depicting Absolute Values

You can view a given absolute value as representing two values, one positive and one negative. Consider, for example, that you begin with an equation such as y = |x|. If you solve this equation for values ranging from 0 to 14, you end up with the graph Figure 7.4 illustrates. The values of x extend in positive and negative directions that reflect distances of the value from zero. The distances can be negative or positive.

##### Figure 7.4. The graph of an absolute value rises to the left and right of the y axis.

When you create a graph in which the points are at equal positions across a given line, they are symmetric with ...
