Introduction

Hyperbolas are a type of conic section that consists of two separate branches, resembling a pair of "tear-drop" shapes. They are defined by a quadratic equation in two variables, typically x and y. In this article, we will explore the process of graphing hyperbolas, identifying their key components, and understanding their properties.

Graphing Hyperbolas

Hyperbolas can be graphed using a variety of methods, including the standard form of the equation. The standard form of a hyperbola is given by:

Horizontal Transverse Axis: $\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} = 1$
Vertical Transverse Axis: $\frac{(y-k)^2}{a^2} - \frac{(x-h)^2}{b^2} = 1$

where (h, k) represents the center of the hyperbola, and a and b are the distances from the center to the vertices.

Graphing the First Hyperbola

The first hyperbola is given by the equation:

$\frac{x^2}{16} - \frac{y^2}{49} = 1$

To graph this hyperbola, we need to identify its key components, including the center, vertices, co-vertices, and foci.

Center

The center of the hyperbola is the point (h, k) that is equidistant from all points on the hyperbola. In this case, the center is (0, 0).

Vertices

The vertices of the hyperbola are the points on the hyperbola that are closest to the center. In this case, the vertices are (±4, 0).

Co-Vertices

The co-vertices of the hyperbola are the points on the hyperbola that are farthest from the center. In this case, the co-vertices are (0, ±7).

Foci

The foci of the hyperbola are the points on the hyperbola that are farthest from the center. In this case, the foci are (±4√14, 0).

Graphing the Second Hyperbola

The second hyperbola is given by the equation:

$\frac{(y+1)^2}{36} - \frac{x^2}{49} = 1$

To graph this hyperbola, we need to identify its key components, including the center, vertices, co-vertices, and foci.

Center

The center of the hyperbola is the point (h, k) that is equidistant from all points on the hyperbola. In this case, the center is (-1, -1).

Vertices

The vertices of the hyperbola are the points on the hyperbola that are closest to the center. In this case, the vertices are (0, -5) and (0, 7).

Co-Vertices

The co-vertices of the hyperbola are the points on the hyperbola that are farthest from the center. In this case, the co-vertices are (-1, ±6).

Foci

The foci of the hyperbola are the points on the hyperbola that are farthest from the center. In this case, the foci are (-1, -5√3) and (-1, 5√3).

Conclusion

Graphing hyperbolas requires a thorough understanding of their key components, including the center, vertices, co-vertices, and foci. By identifying these components, we can accurately graph hyperbolas and understand their properties. In this article, we have explored the process of graphing hyperbolas, including the standard form of the equation and the identification of key components.

Key Takeaways

The standard form of a hyperbola is given by $\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} = 1$ for a horizontal transverse axis and $\frac{(y-k)^2}{a^2} - \frac{(x-h)^2}{b^2} = 1$ for a vertical transverse axis.
The center of a hyperbola is the point (h, k) that is equidistant from all points on the hyperbola.
