Unformatted text preview: y = ), but there are no yintercepts (plug in x = to see why). The dashed lines are the asymptotes of the hyperbola. The two branches approach those lines but never cross them. (Chapter 10: Conics) The graph of y 2 − x 2 = 1 is below: The equation confirms that ± 1 are yintercepts of the graph (plug in x = ), but there are no xintercepts (plug in y = to see why). It helps to remember that: • The graph of x 2 − y 2 = 1 “opens” along the xaxis, while • The graph of y 2 − x 2 = 1 “opens” along the yaxis....
