Let the probability density function of Y be f(y) = {s cy exp(-2y), 0. 0, 0 <y < ; elsewhere. where c is a constant. (a) Find the value of c that makes f(y) a density function. (b) State the distribution of Y, and give the mean and variance for Y. (c) Write down the moment generating function for Y.
