NAME DATE SECTION Introduction to Exponential Functions Checkpoint #3 Checkpoint 3: I can identify function relationships and use function notation to describe & represent and calculate the average rate of change. 1. The graph shows the population of beavers in a forest for different numbers of years after 1995. The beaver population is growing exponentially. a. Explain why we can think of the beaver population as a function of time in years. b. What is the meaning of the point labeled in this context? c. Write an equation using function notation to represent this situation. 2. The graph shows the bacteria population on a petri dish as a function the days since an antibiotic is introduced. 1. What is the approximate value of (4.5)? 2. Approximately what is when () = 400, 000? Explain what you would do, using your usual graphing technology, to be able to see (15)on the graph.
