Use the Chain Rule to differentiate the function. You may need to apply the rule more than once.f(x) = 

A. f'(x) = (7x - (x2 - x + 7)5)3/4[7 - 5(x2 - x + 7)4]
B. f'(x) = (7x - (x2 - x + 7)5)-3/4[7 - 5(x2 - x + 7)4]
C. f'(x) = (7x - (x2 - x + 7)5)3/4[7 - 5(x2 - x + 7)4(2x - 1)]
D. f'(x) = (7x - (x2 - x + 7)5)-3/4[7 - 5(x2 - x + 7)4(2x - 1)]
