Find the volume of the solid formed when the region bounded by the parabola y = x^2 - 2 is rotated about (i) the X-axis (ii) the Y-axis. How exactly do I do this question? For the previous questions, there was a limit for both x and y but now...

How exactly do I do this question? For the previous questions, there was a limit for both x and y but now... For the first part since you are rotating around the x-axis you can find theh intercepts by setting y=0 So your integral becomes Try something similar for the 2nd one.
Thanx
