How do you graph an absolute function?
Recall that the absolute value of a number is its distance from 0 on the number line. To graph an absolute value function, choose several values of x and find some ordered pairs. Plot the points on a coordinate plane and connect them. Observe that the graph is V-shaped.
How do you do absolute value equations?
To solve an equation containing absolute value, isolate the absolute value on one side of the equation. Then set its contents equal to both the positive and negative value of the number on the other side of the equation and solve both equations. Solve | x | + 2 = 5.
How do you graph an absolute value inequality?
When graphing an absolute value linear inequality, first make sure the inequality is in terms of y. Absolute value linear inequalities are v-shaped. To find points on the graph, set up a table of values. Use a wide range of values in order to get points that cover both sides of the "v".
