Using MATLAB, plot the following three equations over the range x in $[2,2]$:

$\%$ Equation $1$

y$1=2*$x$.^2+3*$x $-1$;

$\%$ Equation $2$

y$2=0\mathrm{.}5*$exp$(-0\mathrm{.}2*$x$).*$sin$(2*$x$)$;

$\%$ Equation $3$

y$3=-0\mathrm{.}1*$x$.^3+4*$x$.^2-5*$x $+2$;

Ensure the plot is well$-$labeled with a title, axis labels, and a legend to distinguish between the curves. Submit both your MATLAB code and the resulting plot. Make sure that code gives the given plot.
