Hi guys

My rational funtcion is f(x)= 3x/(x^2-x-6)

Now for this I got the horizontal asymptote as y=0 because the degree of the denominator is greater than that of the numerator ... but how come the x intercept is 0 so it has to pass through zero ... and here is the link for the graph can anyone please help me out here ??

Thank you very much
