$(1)$ Create a MATLAB script to generate and plot the following functions on the interval $2<=$x$<=2$:

$1.$ y$=$ x$^4-4$x$^3+6$x$^2-4$x$+1$

$2.$ e$^(-$x$^2)$

Plot these functions using different line styles and colors, label the axes appropriately, provide a title for the graph, and include a legend to distinguish between the curves.
