For problems 10 and 11, rewrite the equation to highlight important distances between features of the hyperbola and use them to find the asymptotes, the vertices, and foci, and graph the hyperbola.

Go

Classify each equation as a parabola, circle, ellipse, or hyperbola, and then identify the desired features. (Hint: You may rewrite the equation in a different form to highlight the features.)

If the equation is:

  • a parabola, identify the vertex, focus, and directrix.

  • a circle, identify the center and the radius.

  • an ellipse, identify the center and the radius for the horizontal and vertical axes.

  • a hyperbola, write the equations of the asymptotes.
