recall that the form $\displaystyle y=\frac{1}{x}$ is called an

*equilateral hyperbola*

first rewrite the equation as $\displaystyle y=-\frac{3}{x}$ the - sign will flip the graph and the 3 will expand it.

here is graph of $\displaystyle y=\frac{1}{x}$ and $\displaystyle y = -\frac{3}{x}$ - Jun 7th 2010, 05:19 PMrobot214
Thanks so much!
