Conic Sections
Understand the graphs and equations of conic sections.
15.
Create graphs of conic sections, including parabolas, hyperbolas, ellipses, circles, and degenerate
conics, from second-degree equations.

a.
Formulate equations of conic sections from their determining characteristics.
Example:
Write the equation of an ellipse with center (5, -3), a horizontal major axis
of length 10, and a minor axis of length 4.
