Precalculus graphing hyperbolas worksheet
Precalculus starts hyperbolas from the general form, so completing the square comes first. Then it finds the foci with c² = a² + b² and writes the asymptote equations, not just the branches.
Also taught in Algebra 2, at its own level and with its own examples.

How to do these
Find the center and foci of
- Complete the square: 9(x - 1)² - 4(y + 2)² = 36.
- Divide by 36: (x - 1)²/4 - (y + 2)²/9 = 1, so a = 2 and b = 3.
- c² = 4 + 9 = 13, and the x term is first, so the foci sit left and right of the center.
The answer is Center , foci .
Where students go wrong
Using c² = a² - b², the ellipse rule. For a hyperbola c² = a² + b², so the foci always lie farther from the center than the vertices.
Also called plotting hyperbolas, hyperbola graphs or asymptotes of a hyperbola.
