Step-by-step explanation:

Given function:

f(d) = 7(1.06)^dPart A:13.29 = 7(1.06)^d13.29/7 = (1.06)^d1.8985 = (1.06)^dd = log 1.8985 / log 1.06d = 11 daysPart B:

y -intercept is:

f(d) = 7(1.06)^0 = 7*1 = 7 mm

7 mm is the initial radius of the algae

Part C:

Average rate of change from d = 4 to d = 7 is:

(f(7) - f(4))/(7 - 4) =(7(1.06)^7 - 7(1.06)^4)/3 =1.688/3 = 0.563 mm/day

It represents average daily growth of the radius of the algae from day 4 to day 7 period
