Write an equation that models the following situation:
Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

• y=6(0.14)^x
• y=6(1+14)^x
• y=6(1.14)^x
• y=6(0.86)^x

Daniel’s Print Shop purchased a new printer for $35,000. Each year it depreciates at a rate of 5%. How much will the printer be worth in 8 years?

• $23,219.72
• $136.72

Evaluate for f(1)

• 0
• -3
• 3
• 2

Given f(x) =
2x² + 5x - 17, find f(-1). 

• f(-1) = -20
• f(-1) = -24

Identify the domain of the following relation:

• -6, 14, 2, 28
• (-6,14), (0,32), (2,38), (4,44)
