Hyperbola - Graphing • Recall that the equations for a hyperbola are ... Horizontal Axis Vertical Axis
Hyperbola - Graphing • The center of the hyperbola is located at the • point (h, k) ... • Example 1: • Determine the center of • the hyperbola given by ... • The center is at C(7, -3). Slide 2
Horizontal Axis Vertical Axis Hyperbola - Graphing • Note how the position of the a is always with the positive term, and the b is always with the negative term. • Also, when the positive term includes x, the axis is horizontal. When the positive term includes y, the axis is vertical. Slide 3
a a Hyperbola - Graphing • The vertices of the hyperbola are located on the axis ... and are a units from the center. Horizontal Axis Vertical Axis Slide 4
Hyperbola - Graphing • The foci lie on the axis and are c units from the center where ... • Summary: The center is at C(h, k). The vertices are a units from the center on the axis. The foci are c units from the center on the axis. • The remaining techniques for graphing a hyperbola will be shown in the next example. Slide 4
Hyperbola - Graphing • Example 2: • Sketch the graph of the • hyperbola given by ... • The center is at C(-4, 1). • Since the positive term includes the y, the axis is vertical. • The value of c is given by ... Table of Contents Slide 4 © 2000 Alan J. Dinwiddie, Jerry C. Neve
