# second PA is another example of how your growing knowledge of how college algebra will serve you in the future.

I need support with this Algebra question so I can learn better.

Exponential Functions Project

You will need to:

1. Pick one of the following scenarios:

• You buy a new car that cost \$25,000. The car depreciates at a rate of 11% per year.
• You put \$7,500 into an investment account. The account is projected to earn 9% interest per year.
• The population of Kensington is currently 120,000 people. It is growing at a rate of 0.35% per year.
• The population of Camden, NJ is currently 180,000 people. People are moving out at a rate of 1.2% per year.

2. Write an equation to represent the exponential function of the scenario.

3. Create a table to represent the exponential function

1. Identify the growth/decay rate on your table.
2. Explain how the growth/decay rate represents an exponential function.

4. Create a graph to represent the exponential function.

5. Use color to connect and identify “a” and “b” in the table, equation, graph, and scenario.

6. Identify the following:

a. Independent variable

b. Dependent variable

c. Domain

d. Range

e. Starting point

f. Growth/decay rate
