Answer:A f(x) = 1/3x^3Step-by-step explanation:g(x) = x^3We want f(x) to be vertically compressedf(x) = ag(x ) a is vertical stretch/compression
|a| > 1 stretches |a| < 1 compresses so we need to multiply by a number less than between 0 and 1If a is negative it is a reflection, which was not asked forf(x) = 1/3 x^3
