How to find the foci, center and vertices, and asymptotes of a hyperbola

Learn how to graph hyperbolas. To graph a hyperbola from the equation, we first express the equation in the standard form, that is in the form: (x – h)^2 / a^2 – (y – k)^2 / b^2 = 1 for horizontal hyperbola or (y – k)^2 / a^2 – (x – h)^2 / b^2 = 1 for vertical hyperbola.

Next, we identify the characteristics of the given hyperbola. The center of the hyperbola is (h, k). It is halfway between the two vertices and halfway between the two foci. ‘a’ (the distance from the center to the vertices) is the square root of the first denominator and ‘b’ (the distance from the center to the covertices) is the square root of the second denominator. ‘c’ (the distance from the center to the foci) is obtained by taking the square root of the sum of a^2 and b^2. Using these characteristics of the hyperbola, we can graph the asymptotes of the hyperbola and hence graph the hyperbola.

Note that a hyperbola is vertical when it is facing up and down and is horizontal when it is facing right and left.
