The continuous random variable X has the probability density function g:[0,)R,g(x)=xex, and has an expected value of 2 and variance of 2 . The continuous random variable Y has the probability density function h:[0,)R,h(x)=9xe3x. i. The transformation T:R2R2 with rule T([xy])=[a00b][xy] maps the graph of y=g(x) onto the graph of y=h(x). Find the values of a and b
