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
• 3
• -3

Graphing: Absolute Value

• ​Absolute value graphs are not linear.

  ​

• Absolute value graphs looks like a V.

Poll

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

• Horizontally

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

• Left

• Right

• Up

• Down

Open Ended
