Course Portfolio Due June 23rd!

We will continue with our exam review today. We will look at exponential functions:

• exponent, power, base
• exponent rules
• exponential relations

Each group will be assigned one exponent rule to summarize and add to a class table.

How can you simplify the following:

1. (3⁶ ÷3²)÷3⁴
2. (-1335)⁰=
3. (5)^-3

Next we will look at exponential models. What is the general equation for exponential growth/decay? How can you tell if you have growth or decay?

In your group, try these problems:

1. The population of Wikwemikong grows 15% per year. If the current population of the town is 1500 people, what will the population be in three years?
2. Ms. Black’s Rav 4 decreases in value each year by 12%. If it is worth $8000 now, what will is be worth in 5 years?

With the remaining class time, you should be working on your portfolio and/or your exam reviews.
