Of the six questions regarding finding vertical asymptotes of graphs, I've had problems with two. The second is using the graph of $g(x)= \frac{3+x}{x^{2}(3-x)}$
Now, looking at the function, it seems that both 0 and 3 will be the vertical asymptotes, since $g(0)= \frac{3+0}{0^{2}(3-0)}= \frac{3}{0(3)}= \frac{3}{0}= undefined$ and $g(3)= \frac{3+3}{3^{2}(3-3)}= \frac{6}{9(0)}= \frac{6}{0}= undefined$
However, those answers were not accepted, why?
