# Worksheet: Equation of a Hyperbola

In this worksheet, we will practice writing the equation of a hyperbola and finding a hyperbola’s vertices and foci using its equation and graph.

Q1:

A gardener wants to grow a hedge around a fountain in their yard. They decide to plant the hedge along a hyperbola, where one of the foci of the hyperbola is at the fountain. At its closest, the hedge will be a distance of 20 yards from the fountain. Using a coordinate system whose origin is at the fountain and with units in yards, the path of the hedge has asymptotes and . Find the equation of the hyperbola in this coordinate system.
