Absolute Value Function

And Graphs  

Absolute Value Functions II |Linear Inequalities| Absolute value of linear inequalities
Since the absolute value of a number is always positive, when we graph the equation y = |x|  the shape of our graph looks quite different from the graph of y = x. (see the demonstration below for more detail)
