Question

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:

f(n) = 15(1.04)n

Part A: When the scientist concluded his study, the height of the plant was approximately 20.53 cm. What is a reasonable domain to plot the growth function?

Part B: What does the y-intercept of the graph of the function f(n) represent?

Part C: What is the average rate of change of the function f(n) from n = 1 to n = 5, and what does it represent?

Answer 1

I know what Part B is. i just need help with part A+B

Answer 2

I meant C

Answer 3

Is this >> f(n) = 15(1.04)n supposed to be f(n) = 15(1.04) ^n

Answer 4

Yes

Answer 5

I can't help with part C until I know the results of parts A and B.

Answer 6

For part B I put down that it represents the plant height

Answer 8

Okay

Answer 9

Thatis a different problem but notice that the function is exponential.

is f(n)= 8(1.05)^n .

So, I'm asking you to check your equation.

Answer 10

Alright

Answer 11

Thanks
