Explanation / Answer

This function seems to a ever increasing function in the range 1<=x<=5 as the derivative is positive, and therefore x = 5 we will get the highest average cost per unit.

Please note that the range is from 1 to 5, and therefore x=5 is the upper limit to what you can sub the value of x as.

Therefore, 2x^3-42x+288x+12 at 5 = 2*5^3-42*5^2+288*5+12 is 652

Answer is D
