Answer 5

I am not sure what you are working on in class. Usually when I see questions like this they something like what is the volume of the solid revolved around a certain x or y. But you can integrate this, let u=2x^2+1 then when you get dx you can solve for u and substitute for x.

Answer 6

yes that is ture but, the du doesnt cancel out the x that is there cause of the equation
