Write a MATLAB code $($M$-$file$)$ called plotfunc that does the following:

Receives the name of another MATLAB function as an input $($e$.$g$.,$ user defined func$01$ for a function f$($x$)$

$,$ which calculates f$($x$)$

$).$

Plots the function, including a horizontal line at f$($x$)=0$

$,$ so that the user can visually see the roots $($see built$-$in function in MATLAB fplot$()).$

Performs the plot inside a while loop that begins with a default interval $75<=$x$<=75$

and keeps asking the user for new interval limits until the user is satisfied and the loop ends.
