1 describe the inequality graph
To graph ty function simply make a table of values, where you choose any value for x and substitute that value in the function.

It is always positive, the absolute value of -6 is 6 etc.
Then graph the resulting points.
Another way to do it is simply draw the graph of y = |x| then move it 2 spaces to the right and 4 spaces down, I believe.
