1. Warm Up/Review Function and Inverse
Which of the below have an inverse that exists as a function?
Graph each of the below (identify the Domain and Range):

2. Use the Interest Rate formula to solve the below:
You invest $2200 in stock that is projected to grow at a rate of 12.5% compounded monthly. How much will this investment be worth in 6 years?

3. Depreciation
Depreciation is a business tax deduction given for the loss in value of some type of equipment
Formula similar to Int Rate Formula – only it is a Exponential Decay:
Example: Your business purchases a Helicopter for $200,000. How much will it be worth in 12 years if it depreciates at a rate of 20% per year?

4. Solving for Exponents
Exponential Functions with the same base must have exponents that are equal.
Examples: Solve each of the below for x:
