QUESTION TWO

You wish to write a script that will analyze the following function:

$y=\frac{2x^{2}cos(x)}{7-\text{e}\text{x}\text{p}(0\mathrm{.}25x)}$

a$)$ Write the m$-$file, fun$\_$x$.$m$,$ required to define this as a MATLAB

function.

Consider the function

$y=x^2{e}^{-4x}$

b$)$ Write a MATLAB script that will produce a smooth graph of this

function on the interval $x=[0\mathrm{.}3].$ Submit your entire MATLAB

script.
