# Thread: Rational Equation Match it to the Graph?

1. ## Rational Equation Match it to the Graph?

Help me match this graph to the correct equation? I don't know if I am doing it wrong, no equation seems to fit?

Start by noting the horizontal and vertical asymptotes (if there are any), then look for x and y intercepts. Try listing just those and see what kind of function you have to put together to give it those properties.

From the graph notice that $\displaystyle y>0\text{ for }x<4$ and $\displaystyle y<0\text{ for }x>4$.

The answer is in that list.
