1-107.

Sandra is playing around with inverses and thinks she has discovered something interesting. She thinks that if *f*(*x*) = *g*^{–1}(*x*), then the areas of the regions shaded below are equal. Use *f*(*x*) = *x* + 1 with *a* = 3 and *b* = 5 to verify Sandra’s conjecture. Homework Help ✎

Substitute in the values for *a* and *b*. Are the values equal?
