For the region bounded by the curves x=y2 and x=y+2 between y=0 and y=2, a student must decide whether to integrate with respect to x or with respect to y. Which orientation avoids having to solve either curve for the other variable?
a) Both orientations require solving for the other variable.
b) Integrate with respect to x only.
c) Integrate with respect to y only.
d) Neither orientation can be used because the region is not closed.
