$2.$ Consider the following mathematical function:

f$($x$)=1/2$ e$^($x$)$sin$(3\backslash$pi x$)$

Write a MATLAB script to plot this function over the interval x Use a dotted blue line for the curve, set the line width to $2,$ and include labels for the x$-$axis, y$-$axis, and a title for the plot.

Show the resulting plot.
