Problem

The curves

x = y^{2}

and

x = 2y + 3

intersect at two points. For all

y

between the

y

-coordinates of these intersection points, which curve forms the right boundary of the region enclosed by the two curves? a)

x = y^{2}

b) Each curve is the right boundary on a different subinterval of

y

x = 2y + 3

d) Neither curve can serve as the right boundary because the region is not bounded in
