Match the following functions with their types.

• f(x) = 2^x

• Linear

• f(x) = x^2 + 4x + 4

• Exponential

• f(x) = 2x + 3

• Absolute Value

• f(x) = 5 + 3|x - 9|

• Quadratic

Solve. 
|2x - 12| + 8  = 8 

• x = 6 or x = -2

• x = 6 or x = -6

• no solution

• x = 6

What is the first step? 

• Get absolute value alone by subtracting 5 from both sides

• Get absolute value alone by dividing by 5 on both sides

• Split into two equations
