4-88.

Translation: three times the area under *f*(*x*) between *x* = 1 and *x* = 6 + five times the same area. Write this as a single integral.

See hint (a) and then see hint (c).

Since an integral is the area underneath or above a curve, if you take a smaller portion of that area and subtract it from a larger portion, both starting at the same point, what are you left with?
