Provide an appropriate response.Given that A(x) = C(x)/x , where A(x) is the average-cost function and C(x) is the total-cost function, find an expression for A'(x) and solve the equation A'(x) = 0 to find the minimum average cost.

Question

A. A'(x) =  = 0 ? xC(x) - C'(x) = 0 ?   = A(x) = 
B. A'(x) =  = 0 ? xC(x) - C'(x) = 0 ?   = A(x) = 
C. A'(x) =  = 0 ? xC(x) - C'(x) = 0 ?   = A(x) = C(x)
D. A'(x) =  = 0 ? xC'(x) - C(x) = 0 ?   = A(x) = C'(x)
