A hyperbola is a type of conic section that is formed by intersecting a cone with a plane, resulting in two parabolic shaped pieces that open either up and down or right and left. Similar to a parabola, the hyperbola pieces have vertices and are asymptotic. The hyperbola is the least common of the conic sections.

Conic Sections: The Hyperbola part 1 of 2
This video defines a hyperbola and explains how to graph a hyperbola given in standard form.
Conic Sections: The Hyperbola part 2 of 2
This video explains how to graph a hyberbola in general form.
Transformations of a Hyperbola:
Graphing a transformed hyperbola combines the skills of graphing hyperbolas and graphing transformations. With hyperbola graphs, we use the formula a^2 + b^2 = c^2 to determine the foci and y= + or - (a/b)x to determine the asymptotes. When transforming hyperbola graphs, we find the center of the graph and then graph accordingly.
How to transform the graph of a hyperbola.
This video shows how to sketch the graph of a shifted hyperbola.
Conic Section Formulas
We can easily identify a conic section by its formula. Conic section formulas have different identifiers. For example, a vertical parabola has a squared "x" term and single "y" term while a horizontal parabola has a single "x" term and a "y" squared term. An equation for a circle has a squared "x" term, a squared "y" term and identical coefficients.
