Chapter 10: Q. 34 (page 668)

In Problems 29–36, find the center, transverse axis, vertices, foci, and asymptotes. Graph each equation by hand. Verify your graph using a graphing utility. $x^{2} - y^{2} = 4$

Short Answer

Expert verified

$Center : (0, 0) Transverse axis : x - a x i s Vertices : (\pm 2, 0) Foci : (\pm 2 \sqrt{2}, 0) Asymptotes : y = \pm x$

Graph of the equation is:

Step by step solution

Step 1. Given information

Equation of hyperbola, $x^{2} - y^{2} = 4$

Writing the equation in standard form, $\frac{x^{2}}{4} - \frac{y^{2}}{4} = 1$

Step 2. Finding the center, transverse axis, vertices, foci, and asymptotes of hyperbola

Comparing the given equation with standard form, $\frac{x^{2}}{a^{2}} - \frac{y^{2}}{b^{2}} = 1, b^{2} = c^{2} - a^{2}$

We get,

$a = 2, b = 2, c = \pm \sqrt{a^{2} + b^{2}} \Rightarrow c = \pm \sqrt{2^{2} + 2^{2}} \Rightarrow c = \pm \sqrt{4 + 4} \Rightarrow c = \pm \sqrt{8} \Rightarrow c = \pm 2 \sqrt{2}$
