(04.03 mc) a marine biologist is studying the growth of a particular species of fish. she writes the following equation to show the length of the fish, f(m), in cm, after m months: f(m) = 5(1.07)^m part a: when the marine biologist concluded her study, the length of the fish was approximately 9.19 cm. 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(m) represent? (2 points) part c: what is the average rate of change of the function f(m) from m = 1 to m = 9, and what does it represent? (4 points)
