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) = 12(1.03)n

Part A: When the scientist concluded his study, the height of the plant was approximately 16.13 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 = 3 to n = 10, and what does it represent?

Answer 1

Did you write the equation correctly? Is there suppose to be a plus sign between 12 and 1.03?

Answer 2

The N is an exponent.

Answer 3

I just need part c now.

Answer 4

I looks like you just find the slope the line connecting points f(3) and f(10). The slope or average rate of change would be .43 cm

Answer 5

@bvbarmy17 part C

Answer 6

i do believe it is 43 average rate

Answer 7

How did you get that?

Answer 8

I figured it out. Thanks man.

Answer 9

nah no problem

Answer 10

thanks for the medal
