28 ) Create graphs of conic sections, including parabolas, hyperbolas, ellipses, circles, and degenerate conics, from second-degree equations. (Alabama)
Example: Graph x2 - 6x + y2 - 12y + 41 = 0 or y2 - 4x + 2y + 5 = 0.
a. Formulate equations of conic sections from their determining characteristics. (Alabama)
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.
