Equations of hyperbolas worksheet for Precalculus
Precalculus writes hyperbolas from their parts: the center with a vertex and b, the vertices with the foci, or the vertices with the asymptotes, using c² = a² + b². Orientation comes first: the branches open toward the vertices, and the squared term for that direction is the positive one with a² under it.
Also taught in Algebra 2, at its own level and with its own examples.

How to do these
Write the equation of the hyperbola with center , a vertex at and a focus at
- The vertex is 3 to the right of the center, so a = 3 and the branches open sideways.
- The focus is 5 away, so c = 5 and b² = 25 - 9 = 16.
The answer is .
Where students go wrong
Subtracting to find b² as for an ellipse. The foci sit beyond the vertices, so c is the largest and b² = c² - a², here 25 - 9 = 16.
Also called standard form of a hyperbola or hyperbola equation.
