Oct 13, 2025 by leolavanderia.com.br 127 views

In mathematics, a hyperbola is a type of conic section that consists of two separate curves, each of which is a mirror image of the other. The standard form of a hyperbola equation is given by $\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1$ , where $(h,k)$ represents the center of the hyperbola, and $a$ and $b$ are the distances from the center to the vertices along the x-axis and y-axis, respectively.

Identifying the Center and Vertices of a Hyperbola

To identify the center and vertices of a hyperbola, we need to rewrite the given equation in the standard form. The given equation is $\frac{(x-3)^2}{9}-\frac{(y-4)^2}{4}=1$ . By comparing this equation with the standard form, we can see that the center of the hyperbola is at the point $(h,k) = (3,4)$ .

Finding the Values of $a$ and $b$

The values of $a$ and $b$ can be found by comparing the given equation with the standard form. In the given equation, the denominator of the first term is $9$ , which represents $a^2$ . Similarly, the denominator of the second term is $4$ , which represents $b^2$ . Therefore, we can find the values of $a$ and $b$ as follows:

$a = \sqrt{9} = 3$

$b = \sqrt{4} = 2$

Finding the Values of $x_1$ and $y_1$

The values of $x_1$ and $y_1$ can be found by using the formulas $x_1 = h + a$ and $y_1 = k + b$ . Substituting the values of $h$ , $k$ , $a$ , and $b$ , we get:

$x_1 = 3 + 3 = 6$

$y_1 = 4 + 2 = 6$

Therefore, the values of $a$ , $b$ , $x_1$ , and $y_1$ are $3$ , $2$ , $6$ , and $6$ , respectively.

In this article, we have discussed how to find the values of $a$ , $b$ , $x_1$ , and $y_1$ from a given hyperbola equation. We have also identified the center and vertices of the hyperbola and used the formulas to find the values of $x_1$ and $y_1$ .
