Graphing Absolute Value Practice

Use Narrower, Wider, or Same to compare the width of this graph to its parent function.

y = 0.25 |x - 1|+ 2

• Narrower

• Wider

• Same

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|

Describe the transformations of the absolute value equation.

• Graph is wider, reflects over x-axis, shifts right 1 unit

• Graph is wider, reflects over x-axis, shifts up 1 unit

• Graph is more narrow, reflects over x-axis, shifts right 1 unit

• Graph is more narrow, reflects over x-axis, shifts up 1 unit

What is the range of the absolute value function?

• (-infinity, infinity)

• [3, infinity)

• [0, infinity)

• (-infinity, 3]

Is the line for the inequality

f(x) ≥|x+3|- 9 going to solid or dotted?

• Dotted

• Solid

Use Narrower, Wider, or Same to compare the width of this graph to its parent function.

y= 1/3 |x| + 3

• Narrower

• Wider

• Same

Describe the transformation from the Absolute Value Parent Function.

• Graph is more narrow, shifts up 4 units

• Graph is more narrow, shifts down 4 units

• Graph is wider, shifts up 4 units

• Graph is wider, shifts down 4 units

What is the equation of the absolute value function?

• f(x)= |x+4|

• f(x)= |x-4|

• f(x)= |x| + 4

• f(x)= |x| - 4
