Practice Problem: Obtain the moment generating function for an exponential random variable
Let X be an exponential random variable. Recall that the pdf of an exponential random variable is given by
$ \ f_X(x)= \lambda e^{-\lambda x}, \text{ for }x\geq 0 . $
Obtain the moment generating function $ M_X(s) $ of X.
