Exercise $6$

$($a$)$ Enter the function $g(x,y)=\frac{x^4}{y^2}+\frac{cos(2x{e}^{9y})}{x^3+7}$ as an anonymous function. Evaluate the function at $x=-8$ and $y=5$ by entering $g(-8,5)$ in the command window.please provide a best matlMatlab codes not used a chattggpt please and pl$.$For both parts

$($b$)$ Type clear $g$ to clear the value of the function from part $($a$).$ Now write a function $M-$file for the function $g(x,y)=\frac{x^4}{y^2}+\frac{cos(2x{e}^{9y})}{x^3+7}.$ Save the file as $g*m($include the M$-$file in your report$).$

Evaluate the fiuction at $x=-8$ and $y=5$ by entering $g(-8,5)$ in the command window.
