Refer to the graph of the hyperbola shown below. Hint: the foci are at (-1, -2 + (41) and are indicated in red. Y 10 8- -10 8 6 4 -2 0 2 4 6 8 10 The center is at ( The distance from the center to the vertices (a) is units. b = The equation of the hyperbola is Use ^ before exponents: x2 would be written x^2
