a) Use the Product Rule to find the derivative of the given function b) Find the derivative by multiplying the expressions first. F(x) = 9x (x# - 7x) a) Use the Product Rule to find the derivative of the function, Select the correct answer below and fill in the answer box(es) to complete your choice O A. The derivative is 9x6 + 270x O B. The derivative is 9x 1 + (x - 7X) ( ) O C. The derivative is (x* - 7x) O D. The derivative is 9x (x4 - 7x)() b) Multiply the expressions. 9x6 (x4 - 7x) =(Simplify your answer ) Now take the derivative of the answer from the previous step and simplify the answer from part a Check to make sure that the two results are the same That is, using either approach, F'(x) =]
