What is the equation of the absolute value function?

• f(x)= 4|x+3|

• f(x)= 1/4 |x+3|

• f(x)= 1/4 |x - 3|

Describe the transformation from the Absolute Value Parent Function. Select all that apply.

• translate 4 right

• translate 4 down

• Vertical compression by factor 1/5

• Vertical stretch by factor of 5

• Horizontal stretch by factor of 5

Answer explanation

1/5 is OUTSIDE the absolute value, so it is a vertical compression.

subtract 4 is OUTSIDE the absolute value, so it is vertical translation.

Vertical transformations are how they appear in the function.

Answer: Vertical compression by a factor of 1/5, Translate down 4
