Consider a region R bounded by the functions f(x) = x2 + 1 and g(x) = x over the interval [0, 2]. (a) Draw an accurate graph of the region R. (b) Find the area of the region. (c) A solid of revolution is obtained by revolving a plane region bounded by a curve f(x), x ∈ [a, b], about x-axis. The volume of such solid is as V = π∫a b [f(x)]2 dx. Calculate the volume of the solid generated by the region R revolving about the x-axis.
