Q$2.$ Write a MATLAB implementation that applies the Simpson's $\frac{3}{8}$ rule to find an approximation widehat$(I)$

for

$I={\displaystyle \underset{a}{\overset{b}{}}}{x}^4{e}^{7x}dx,$

and that gives the relative error percentage between widehat$(I)$ and the exact value derived by the

integral command, as the output. Any unknown values are to be taken from the user. Fill

the following table:
