9-112.

Find the area of the region bounded by the curves *f*(*x*) = *x *+ 1, *g*(*x*) = *x*^{2} − 1, and *h*(*x*) = cos^{−1 }*x *which includes the origin. Homework Help ✎

Graph the curves and determine the points of intersection.

For the second integral, use integration by parts.

Let *f* = cos^{–1}(*x*) and *dg* = 1*dx*.
