Expected Value of a Function of X. To find E[ f(X) ], where f(X) is a function of X, use the following formula The standard deviation of X is the square root of Var(X). Note that the variance does not behave in the same way as expectation when we multiply and add constants to random variables. The limit from the right of 2 and the limit from the left of 2 are not equal therefore the given limit DOES NOT EXIST. Solution to Example 9: We first factor out 16 x 2 under the square root of the denominator and take out of the square root and rewrite the limit as.
