The deeper you are under water; the less sunlight reaches you. The percent of sunlight, P, that reaches a depth d, in metres, can be modelled by the function p(d)=100(0.85)^d a) Graph P(d) for the interval [0, 10] in paper-pencil-ruler style. b) Graph the inverse of P on the same grid in paper-pencil-ruler style. c) Use your graph of the inverse of P to determine the depth at which the percentage of sunlight is 50%. Test your value for depth in the original equation for P .
