Abiologist 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 a days:
f(d) = 9(1.04)
part a: when the biologist concluded her study, the radius of the algae was approximately 12.81 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 = 3 to d = 9, and what does it represent? (4 points)
