Solve the problem.Suppose that the average monthly low temperatures for a small town are shown in the table.
Model this data using f(x) = a sin(b(x - c)) + d. Use the sine regression feature to do this. Approximate all values to one decimal place.
A. f(x) = 25.7sin (0.5(x + 1.6)) + 32.5 B. f(x) = 22.5sin (0.5(x + 3.2)) + 40.7 C. f(x) = 22.5sin (0.5(x + 1.6)) + 40.7 D. f(x) = 22.5sin (1.25(x + 1.6)) + 40.7
