PLEASE IM BEGGING! HELP! A biologist is studying the growth of a particular species of algae. She writes the following equation to show the radius of the algae, f(d), in mm, after d days: f(d) = 11(1.01)^d
Part A: When the biologist concluded her study, the radius of the algae was approximately 11.79 mm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(d) represent? (2 points)
Part C: What is the average rate of change of the function f(d) from d = 2 to d = 7, and what does it represent? (4 points)how and why the concept of private property developed

In this case, a reasonable domain to plot the growth function - 6.97, the y-intercept of the graph of the function f(d) represent = 11 (initial numbers), and the average rate of change of the function f(d) from d = 2 to d = 7 = 0.11447.

Given:

f(d) = 11  

Part A:  

f(d) = 11.79  

11.79=11  

= 11.79/11  

= 1.071818  

d =  

d = 6.97

Part B:  

y- intercept is obtained when domain = 0  

d = 0 ⇒ f(0)

= 11(1.01)⁰

= 11*1 = 11  

f(d) = 11

Part C:  

The average rate of change -  

Thus, a reasonable domain to plot the growth function - 6.97, the y-intercept of the graph of the function f(d) represent = 11 (initial numbers), and the average rate of change of the function f(d) from d = 2 to d = 7 = 0.11447.

Part A: after 9 days the radius of the algae would be 12.81mm so the domain is 9. you would plot the domain at (0,9)

Part B: the y-intercept (the 9) represents the amount of algae the experiment started off with.

Part C: the rate of change is 0.

Step-by-step explanation:

i would say c is the best answer, hope it's right!

good luck! =)
