Researchers used a version of the Gompertz curve to model the growth of razor clams during the first seven years of the clams’ lives with the equation L(t) = Be^-ce-kt, where L(t) gives the length (in centimeters) after t years, B = 14.3032, c = 7.267963, and k = 0.670840. Find the inflection point and describe what it signifies.
