Semester Final Review

What is the equation of the graph below?

• f(x) = I x + 2 I 
• f(x) = I x + 2 I +2
• f(x) = I x - 2 I +2
• f(x) = I x - 2 I 

Evaluate this function for x=2

• f(2) = 4
• f(2) = 3
• f(2) = -3
• f(2) = 5

Describe the transformation of the equation below from the parent function of y = IxI
y = I x + 2 I - 5

• Left 2 up 5
• Right 2 up 5
• Left 2 down 5
• Right 2 down 5

Evaluate the following expression:
-3x² - 5x + 7 when x = -2

• 5
• 10
• 12
• 7

Solve for x
l 2x−1 l = 9

• x = 5 and x =-4
• x = 5 and x = -5
• Only x = 5
• No Solution

Solve for x
2 lx−4l+8=18

• x = 9 and x =-1
• x = 1 and x = -9
• x= 4 and x = -2
• No Solution

2 < 6z - 10 < 20

• -2 < z < -5
• z > 2 or z < 5
• 2 > z > 5
• 2 < z < 5

x + 2 < -4 or -5x < -15

• -6 < x < 3

• x < -3 and x > 6

• x < -6 or x > 3

• No Solution

-4x - 7 ≥ 21

• x≥7
• x≥-8
• x≤8
• x≤-7

ax + c = R
(solve for x) 

• ax = R + c
• ax = R - c
• x = a(R-c)
• x = (R-c) / a
