Which of the following is the equation for the graph shown?

Nina [5.8K]

The equation of the hyperbola is $\frac{x^2}{4} -\frac{y^2}{12} = 1$

<h3>How to determine the equation of the graph?</h3>

The points on the graph are given as:

(2, 0) and (-2, 0)
(4, 0) and (-4, 0)
Lines at: x = 1 and x = -1

The hyperbola can be represented as:

$\frac{x^2}{b^2} -\frac{y^2}{a^2} = 1$

The points (2, 0) and (-2, 0) means that:

$b = \±2$

Square both sides

$b^2 = 4$

So, we have:

$\frac{x^2}{4} -\frac{y^2}{a^2} = 1$

Also, we have:

a^2 = c^2 - b^2

Where c = 4

This gives

a^2 = 4^2 - 4

Evaluate

a^2 = 12

Substitute a^2 = 12 in $\frac{x^2}{4} -\frac{y^2}{a^2} = 1$

$\frac{x^2}{4} -\frac{y^2}{12} = 1$

Hence, the equation of the hyperbola is $\frac{x^2}{4} -\frac{y^2}{12} = 1$
