Topic 6 Part 2 REVIEW : Exponential Functions

Suppose a population of 42 frogs doubles in size every month. Use the exponential formula to find how many frogs will there be after 15 months?

Does the following table or rule represent a linear or an exponential function?  Explain your reasoning. 

The table is ​ (a)   because it has a ​ (b)   .

• linear
• constant rate of change
• exponential
• constant ratio
• neither
• no pattern
