Relationship Between Hyperbola Parameters
Consider the equation of a hyperbola ((x - h)2 / a2) - ((y - k)2 / b2) = 1, where (h, k) is the center of the hyperbola, a is the distance from the center to the vertex of the hyperbola, and c is the distance from the center to the foci of the hyperbola. How do we find b?
AThere is not enough information to find b.
BWe use the fact that b = c to find b.
CThere is a relationship between h, k, and b that is h + k = b. We use this to find b.
DThere is a relationship between a, b, and c that is b2 = c2 - a2. We use this to find b.
