we have the function


y=(x+2)/(x^2+8x+15)

Simplify


x^2+8x+15=(x+5)(x+3)

substitute


y=(x+2)/((x+5)(x+3))

Remember that

The denominator cannot be equal to zero

so

The domain of the given function, are all real numbers, except for x=-5 and x=-3

that means

There are vertical asymptotes at x=-5 and at x=-3

No holes in the graph

therefore

The answer is the option D
