Module 7 - Exponentials

Match the following formulas with the scenarios that would use them to find the answer:

• The population in Syracuse, NY grows 4% each year.

• Jim invested $400 in an account giving 7.1% interest, compounded quarterly

• The value of a car depreciates 18% each year

• Karen deposited $700 in an account that earns 2.3% interest, compounded continuously

• State the transformations and graph the function

Jared invested $800 in an account that earns 4.2% interest compounded monthly. How much money will he have in 5 years? Round your answer to the nearest cent.

Just type the number in as your answer, no $.
