1. Evaluate the following.

   1. [4 points] ${\int }_{-1}^3{\int \; <!--\; nolimits\; -->}_0^3{\int \; <!--\; nolimits\; -->}_0^{2}x{y}^2{z}^3\mathit{𝑑𝑧}\mathit{𝑑𝑦}\mathit{𝑑𝑥}$.
   2. [3 points] ${\int }_0^1{\int \; <!--\; nolimits\; -->}_0^x{\int \; <!--\; nolimits\; -->}_0^{1}y{e}^{\mathit{𝑥𝑧}}\mathit{𝑑𝑧}\mathit{𝑑𝑦}\mathit{𝑑𝑥}$.
   3. [3 points] Evaluate ${\iiint }_E{e}^z\mathit{𝑑𝑉}$ where $E$ is enclosed by the paraboloid $z=1+x^2+y^2$, the cylinder $x^2+y^2=4$, and the $\mathit{𝑥𝑦}$-plane.
