Show that the result given in exercise 3.158 also holds for continuous random variables. that is, show that, if y is a random variable with moment-generating function m(t) and u is given by u = ay + b, the moment-generating function of u is etbm(at). if y has mean μ and variance σ2, use the moment-generating function of u to derive the mean and variance of u.
