I just need help finding on where the hyperbola starts/ends. The equation:

A hyperbola is the set of points in a plane the difference of whose distances from

two fixed points, called foci, is constant.

Step-by-step explanation: 4 illustrates the two branches of a hyperbola. The line through the

foci intersects the hyperbola at two points, called the vertices. The line segment that

joins the vertices is the transverse axis. The midpoint of the transverse axis is the

center of the hyperbola. Notice that the center lies midway between the vertices, as

well as midway between the foci.

answer:

sometimes
