To graph the equation y = 3x + 2, first, note that the absolute value function x takes the value of x if x is positive or zero, and the negative of x if x is negative.

For x ≥ 0 (when x is nonnegative): y = 3x + 2 y = 3x + 2

For x < 0 (when x is negative): y = 3x + 2 y = 3x + 2
So, the graph consists of two lines:
 A line with slope 3 and yintercept 2 for x ≥ 0
 A line with slope 3 and yintercept 2 for x < 0
Plot these lines on the graph to represent the absolute value function.

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
