factor the denominater
you get (x+3)(x-1)
VA = -3 and 1
so C is the answer

A vertical asymptote would occur if the denominator of the expression was zero while the numerator wasn't. The equation would be x=something, since this provies a vertical line. The denominator term as roots of (x+3) and (x-1), at which points the numerator is finite. So the equations are given by choice 3.

I'm not going to answer your question (mostly because I've forgotten how to do this with without calculus), but I'm going to clarify a major syntax error you have. Make sure you properly differentiate the numerator and denominator.
Your equation should be written:
f(x) = (2x+3)/(x^2+2x-3)
I know that this is how it should be written since I solved the problem (using calculus) and got C for an answer.

Vertical asymptotes, set denominator = 0
x^2 +2x - 3
(x+3)(x-1)
VA are -3 and 1
