Absolute Value Function

And Graphs  

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)
    The graph of every linear (not quadratic etc..) absolute value always has a "V" or a sideways "V" shape. This "V" is the result of the negative absolute values becoming positive. 

 

Practice Problems


Step 1: Fill in x and y values of points on the graph to determine the correct equation.
