When graphing the absolute value function, create a t-chart and list values for x. Then plug those values into the equation to find y.

graph y=abs(x)

Be sure to treat the absolute value like a parenthesis and perform the order of operations using it as a grouping symbol. Anything within the absolute value is performed first.

graph y=abs(x+3)

Once you have practiced graphing several absolute value equations and understand its behavior, you can check your work using a graphing calculator or an online graphing calculator like Desmos.
