Thank you for the opportunity to help you with your question!

Rationional function for the given graph is 

f(x)=[a(x-b)/(x-c)(x-d)]      

As vertical asymptotes are at x=-4,4(Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a  rational function)

Rational function is zero at x=-2

Thus,

f(x)=a(x+2)/(x+4)(x-4)=a(x+2)/(x^2-16)

Please let me know if you need any clarification. I'm always happy to answer your questions.
