can you just help me on the second part? @jigglypuff314

1.Create an exponential growth function, f(x), to model a population of frogs that is growing every year. Identify the principal amount, the growth rate, and the appropriate domain and range for your function. Explain how these key features would affect the graph of f(x).

2.Using your function f(x) from question 2. Demonstrate and explain how to find the average rate of change between year 3 and 5, and between year 5 and 7. Explain what the average rate of change represents to the frog population.

what was the function you had?

anonymous · Answer

i had Here's a function: y = 200(1.03^4.
200 is the initial number of frogs
1.03 means that the number of frogs is increasing by 3% per year
and the 4 = # of years, 4 years
Therefore y gives you the total number of frogs after 4 years, if you were to start with 200 frogs and they increase by 3% per year.
