A scientist is studying the growth of a particular species of plant. He writes thr following equation to shoe the height of the plant f(n), in cm, after n days f(n) = 12(1.03)^n
Part A: When scientist concluded his study, the height of the plant was approximately 16.13cm. 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?
