Evaluate Absolute Value Functions

Evaluate: |-12|

• 12

• -12

• 0

• 1.2

Solve for x
l x−6 l + 4= 10

• x = 12 and x = 0

• x = 3 and x = -3

• x = -12 and x = 0

• No Solution

∣ 2x + 9 ∣ = 15

• x = 3 

• x = 3
  x = -6

• x = 3
  x = -12

• x = 6
  x = -12

• {4, -4}
• {9, -9}
• {5, -9}
• {13, -1}
