Understanding Hyperbolas and Their Properties

The video tutorial on mathguide.com explains how to graph hyperbolas, highlighting the differences from ellipses. It covers identifying the center, using bottom numbers to determine graph points, drawing rectangles and asymptotes, and finally sketching the hyperbola. The tutorial also explains how to find the foci and derive the equation of asymptotes, providing a comprehensive guide to graphing hyperbolas.

What is the main difference between the equations of an ellipse and a hyperbola?

• The presence of a multiplication sign.

• The presence of a division sign.

• The presence of a minus sign.

• The presence of a square root sign.

How do you determine the center of a hyperbola?

• By taking the square root of the coefficients.

• By taking the opposite of the values inside the parentheses.

• By taking the sum of the coefficients.

• By taking the average of the coefficients.

What is the first step in using the denominators to graph a hyperbola?

• Add the denominators together.

• Multiply the denominators.

• Take the square root of each denominator.

• Subtract the denominators.

What shape is created using the points derived from the denominators?

• A circle

• A triangle

• A rectangle

• A hexagon

How do you determine the orientation of a hyperbola?

• By the number of vertices.

• By the first term in the equation.

• By the size of the denominators.

• By the color of the graph.

What are the points called that are closest to the center of a hyperbola?

• Foci

• Vertices

• Midpoints

• Endpoints

What formula is used to calculate the asymptotes of a hyperbola?

• Slope-intercept formula

• Quadratic formula

• Point-slope formula

• Pythagorean theorem
