Absolute Value Transformations Review

Describe the transformation that is applied to the parent function.

f(x) = IxI -5

• Translate left 5

• Translate right 5

• Translate up 5

• Translate down 5

Write the equation for a graph that vertically shrank by a factor of 2/5 and translated up 6.

• y=6|x|-2/5

• y=2/5|x|+6

• y=2/5|x+6|

• y=2/5|x-6|

Describe the transformation of the equation below from the parent function of y = I x I

y = -2 I x - 3 I + 3

• reflect over x axis, vertical stretch by 2, translate right 3 and up 3

• reflect over x axis, vertical stretch by 2, translate left 3 and up 3

• reflect over x axis, vertical shrink by 2, translate right 3 and up 3

• reflect over the x axis, vertical shrink by 2, translate left 3 and up 3

Choose the equation that best matches the graphed function.

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

Describe the transformations of the absolute value equation.

• Reflects over x-axis, compresses wider, shifts right 1 unit
• Reflects over x-axis, compresses wider, shifts up 1 unit
• Reflects over x-axis, stretches more narrow, shifts right 1 unit
• Reflects over x-axis, stretches more narrow, shifts up 1 unit

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|
• f(x)= 4|x - 3|
