1. The problem statement, all variables and given/known data The cost production function as output, x, in 000's(where x>1.000) is given by the function f(x)= 8x^3 + (352/x^2)-6x +6350 2. Relevant equations USE THE EXCEL SOLVER function o determine the value of x which minimizes the cots. What is the cost at this point? What values of x will cause the cost to double? 3. The attempt at a solution I have found the derivative of this function to be : F'(x)= -704/x^3 + 24x^2-6 How do you solve this sort of function to find the minimum value of x? If it was a squared only function, I could use the quadratic formula to find the inflection points, but this one after the first derivative is raised to the power of 3, what is the next step????
