What will be the values of $"x","y","a","c","d",$ and $"e"$ be after running this code?

Function:

function $[x,y,z]=$ myVariableTracker$2(a,b,c,d)$

$x=a+b+c$;

$y=\frac{x}{d}$;

$z=x+y$;

end

Script:

& Using myVariableTracker$2$

$b=1$;

c $=1$;

$d=4$;

e $=2$;

$[x,y,d]=$ myVariableTracker$2(b,c,d,e)$;
