Parts of Absolute Value Functions

Choose the equation that best matches the graphed function.

• Shifted left 10

• Shifted right 10

• Shifted up 10

• Shifted down 10

The blue graphs is the parent function f(x)=|x|, the red must be

• g(x)=|x+2|

• g(x)=|x|+2

• g(x)=|x-2|

• g(x)=|x|-2

Name the parent function. 

• constant

• square root

• linear

• absolute value
