Rational Function

Find a rational function that represents a graph that has a vertical asymptote at x=2 and x= -3 and a horizontal azymptote at y=0.
the answer is f(x)= (x-4)/(x2+x-6) 
I understand how the denominator was found but I am unsure about the numerator. 
Thank you for the help

The question never mentioned an x-intercept.  This is where the numerator comes into play.  Without knowing that, you cannot find the appropriate numerator.
The x-intercept is found by setting the numerator to zero.
