Question

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.

Answer 1

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.

Answer 2

help

Answer 3

Plug in 3 and 5 in the equation. That 4 can change to x.

Answer 4

To be any year.

Answer 5

ok

Answer 6

thxbro

Answer 7

no problem. The equation of avg rate of change is f(2)-f(1)/ t2-t1. For 2 means final and 1 means initial.

Answer 8

Have you learnt this?

Answer 9

yes but im really bad at this lesson thx

Answer 10

T means time.

Answer 11

ik
