Ty's house is worth $100,000 right now. It will lose value at a rate of 2% per year.

Which function models this situation?

• f(x) = 100,000(2)^x

• f(x) = 100,000(1.02)^x

• f(x) = 100,000(0.98)^x

• f(x)=100,000(98)^x

The following function represents a bank account. 
g(x) = 200(1.25)^x
What is the rate the bank is paying?
*Remember the rate is added or subtracted to 1 inside parenthesis*

• 200%
• 1.25%
• 25%
• 2%
