We've been studying LINEAR FUNCTIONS, now it's time to look at "V" shaped graphs. They're called ABSOLUTE VALUE FUNCTIONS.

Multiple Choice

Evaluate the expression.
|-2| + |-5|

• 7
• -7
• 3
• -3

Graphing: Absolute Value

• ​Absolute value graphs are not linear.

  ​

• Absolute value graphs looks like a V.

ABSOLUTE VALUE TRANSFORMATIONS

Multiple Choice

WHAT ARE THE 3 PARAMETERS?

• ahk

• aki

• amb

• amk

Multiple Choice

If a is less than 1, the graph will _____________?

• no change

• stretch

• shrink

• reflect

Poll

If "a" is greater than 1, the graph will stretch ___________?

• Horizontally

• Vertically

Multiple Choice

True or False: Parameter "h" tells us about the horizontal translation

• True

• False

Open Ended

In what direction will the graph translate if parameter "h" is positive?

Multiple Choice

Parameter "k" tells us how the graph will translate Vertically. Which if "k" is negative, in what direction will the graph translate ?

• Left

• Right

• Up

• Down

Open Ended

When is the ONLY time the graph will reflect over the x-axis?

Open Ended

Name one way that you are going to remember parameter "h" from parameter "k".
