Given that a. Find the value of x and the value of y when dy/dx = 0.

Question:

Given that

a. Find the value of x and the value of y when dy/dx = 0.

b. Show that the value of y which you found is a minimum. The finite region R is bounded by the curve with equation y = x^3/2 + 48/x, the lines x = 1, x = 4 and the x-axis.

c. Find, by integration, the area of R giving your answer in the form p + q ln r, where the numbers p, q and r are constants to be found.
