5 w 2 m VW = 3/2 5w 7 W VW 7 w 1/2 1/2 w -1/2 -1/2 9w Step 2 Therefore, we have y = 5 w2- 7w+ 9 = 5W3/2 - 7w1/2+ 9w-1/2 w Now, since the function is a sum of power functions, we can use the Power Rule to find its derivative. Recall that according to the Power Rule, the derivative of wh, where n is any real number, is nw? T . To use the Power Rule, we'll have to calculate the following. m N 1 = - 1 = In H N 1 = Applying the power rule, we have the following. y = w 1/2 _ w- 1/2 + W -3 / 2
