    \[\huge \left(\frac{x}{a}\right)^2+\left(\frac{y}{b}\right)^2=1\] See the addition sign between them? Hmm I don't think that quite matches what we're looking for.

    Hyperbola has form \[\frac{(x-h)^2}{a}+\frac{(y-k)^2}{b}=1\]

    Sorry everyone, mistype Hyperbola form is \[\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1\]

    I find these a little confusing because of all the extra numbers they throw at you. The -1 in x -1 just represents a horizontal shift to the right 1 unit. It doesn't affect the SHAPE of the graph at all. So I would recommend ignoring data like that. It might help you to see what's going on. The function essentially looks something like this,\[\huge \left(\frac{x}{a}\right)^2-\left(\frac{y}{b}\right)^2=1\]
