When light strikes the surface of a medium such as water or glass, its intensity decreases with depth. The Beer-Lambert-Bouguer law states that the percentage of decrease is the same for each additional unit of depth. In a certain lake, intensity decreases about 75% for each additional meter of depth.  (b) Use a formula to express intensity I as an exponential function of d. (Use I0 to denote the initial intensity.)
