To graph an equation as given:

The absolute value of a number (positive or negative) is always the positive number:

Give values to x and calculate the corresponding value of f(x) or y
x= -4

x= -2

x=0

x= 2

x= 4

Use the next points to grpah the equation: (x,y)
(-4,4) (-2, 2) (0, 0) (2, 2) (4 , 4)
Graph of the equation:
