(d) Find any vertical asymptotes, and holes.
Only points to consider are x=-5,2 , zeros of denominator. As numerator does not contain any variable term , hence both points will serve as vertical asymptote and there is no holes.
Vertical asymptotes :- x=-5 and x=2
As x approaches -5- , f(x) approaches +∞
