Unit 8 Review Absolute Value Function and Piecewise Functions

What is g(7) if:

• -17
• -13 
• 13       
• 17

Evaluate the function when x = 6 

• f(6) = -5
• f(6) = 4
• f(6) = 2
• f(6) = 7

What is g(-2) if:

• -7

• 7

• 1

• -1

Which piecewise function corresponds to this graph? (Take your time)

• f(x) = { x  if x < 4;   -x+1  if x ≥ 4
• f(x) = { x  if x ≤ 4;  -x+1  if x > 4
• f(x) = { -x+1  if x < 4;  x  if x ≥ 4
• f(x) = { -x+1  if x ≤ 4;  x if x > 4

Which function is graphed?

• f(x) = 2|x + 2| -4
• f(x) = 2|x - 4| + 2
• f(x) = |x + 2| - 4
• f(x) = -2|x - 4|

Which function is graphed?

• f(x) = -|2x - 3| + 5
• f(x) = -|x + 5| - 3
• f(x) = -|2x + 6| + 5
• f(x) = -2|x + 5| - 3

y = |x| - 7 makes the graph slide . . .

• left 7
• right 7
• up 7
• down 7

y = |x - 3| makes the graph slide . . .

• left 3
• right 3
• up 3
• down 3

How is the equation different from the parent graph?
y = ∣x-5∣+7

• Right 5, down 7
• Right 5, up 7
• Up 5,  right 7
• Down 5, right 7

y=|x+1|−4

• A

• B

• C

• D
