Understanding Hyperbolas

What is the center of the hyperbola given by the equation x^2/4 - y^2/25?

• (0, 2)

• (2, 0)

• (2, 2)

• (0, 0)

How do you determine the orientation of the transverse axis for the hyperbola x^2/4 - y^2/25?

• By the difference in the denominators

• By the order of the terms

• By the sign of the equation

• By the coefficients of x and y

When graphing a hyperbola, what is the purpose of constructing a rectangle?

• To find the center

• To determine the vertices

• To help sketch the asymptotes

• To calculate the foci

What is the value of b for the hyperbola x^2/4 - y^2/25?

• 2

• 5

• 4

• 25

How is the distance to the foci (c) calculated for a hyperbola?

• c = a + b

• c^2 = a^2 + b^2

• c^2 = a^2 - b^2

• c = a - b
