Math III Warm Up 3/20/14
• Classify the following as a(n) circle, ellipse, or hyperbola:
• Give the equation of the following graphs:
Parabolas

Definition (OLD): an equation in the form of or

Definition (NEW): The set of all points in a plane that are equidistant from a fixed line (directrix) and a fixed point (focus) which is not a line.

Lattice Points: points equidistant (2p) from the focus on the parabola

Write the following in standard form, find the vertex, directrix, and focus, then graph.

1. 2.

1. Write the standard form of the equation of the parabola whose directrix is x = -1 and whose focus is at (5, -2).Hint: GRAPH!
1. Write the standard form of the equation of the parabola whose vertex is (-2, 4) and whose focus is at (-2, 3).

Taylor reed is awesome!
