Use Matlab please help! Create a function called Problem$4$ that have input $x$ and output $y.$

Function $y=$Problem$4(x)$

For $x=[8$:$2$:$20],$ valuate vector $y$ such that

$y(x)=(-2x^3+7\sqrt[\phantom{2}]{x})e^{-0\mathrm{.}5x}$

Determine sum $Y$ such that sum $Y$ is the sum of all element value of vector $y.$ Hint:

${\displaystyle \underset{?}{\overset{?}{}}}Y={\displaystyle \underset{?}{\overset{?}{}}}(y).$

Copy your value sump to the blank.

sum $Y=$
