(#1) Consider the solid bounded below by z = x² and above by z = 4-y². If we were to project
this solid down onto the xy-plane, you should be able to use algebra to determine the 2D
region R in the xy-plane for the purposes of integration. Which ONE of these limite of
integration would correctly describe R?
(a) y: x24x: -22
-
(b) y: 22 x: 04-y²
(c) y: -√√4-x2.
→√√4x²x: −2 → 2
(d) z: 24-y² y: -2 → 2
(e) None of the above
