I need help badly, please help?
3. 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.

(x) = 200(1.03^4
was my equation I used before. How would I figure this out??? I don't understand.

phi · Answer

you should "tweak" your function
f(x)= 200(1.03)^x  <---  notice you want an "x" in the equation.

200(2.03)^4 is not a function of x because there is no x!

phi · Answer

find the average rate of change between year 3 and 5

that means find  (f(5) - f(3))/(5-3)
f(5) is short for :  in your equation, replace x with 5, and do the arithmetic
For example, using f(x)= 200(1.03)^x , we would do
f(5)= 200(1.03)^5

if you type into google 
200(1.03)^5 =
it will give you the answer 231.854815

do the same for f(3)

then subtract the two numbers.  that is how much your function changed.
divide by 5-3  (i.e. divide by 2) to get the average rate of change per year.
