There are several cases where we need to plot functions of more than one variable. For example, the following function depends on two independent variables x and y :

f$($x$,$y$)=(1$x$2+$y$3)$e$($x$2+$y$2)2$

The matplotlib package has several useful built$-$in packages to generate such plots. There are several different types of contour$-$like plotting functions available in matplotlib. Personally, I like pcolor, as it directly displays the value in each pixel $($without any smoothing functions$).$ Your goal is to use pcolor to generate a two$-$dimensional plot of f$($x$,$y$)$ for values of x in $[3,3]$ and y in $[3,3].$

Please fill in the parts of the missing parts of the code block below. Note that I recommend using both the linspace$()$ and meshgrid$()$ functions from the numpy package to help you generate a two$-$dimensional grid of points on which f$($x$,$y$)$ can be evaluated. These functions have already been imported at the start of the code block. We have also imported the exp$()$ function, which can be used to evaluate the exponentional operator.
