Show the work you have done on the question.
Find the volume of a solid whose base is bounded by y=x+1, and y=x^2-1. Whose cross sections are taken perpendicular to the x-axis and are squares.
I think I got it mostly right but I'm just not 100% sure about the setup of the question, once thats done the actual integrals are generally easy enough to solve.
v=∫(-1 to 2)x^4-2x^3-3x^2+4x+4 dx
v=(1/5)x^5+(1/2)x^3-x^3+2x^2+4x (-1 to 2)<---- intersection points
=12.4 not sure if this is correct though.
