sorry emptyset.. but i dont understand the part where u wrote $\displaystyle \int_{4}^{16}u^{-\frac{1}{2}}du$

isnt it suppose to be 3 on top and -1 below? - Jun 3rd 2010, 07:11 PMDiemo
Those are the limits for x, but you are now working with the variable u = 3x+7.

Check out what the values of u are when x=-1 and x=3.
