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

  2. Day 1 Mm2g2c - Conics: Parabolas

  3. What do you know about parabolas?

  4. 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

  5. Equation: ___________________________ p > 0, opens: _____________________ p < 0, opens: _____________________ Vertex: __________________________ Focus: __________________________ Directrix: ________________________ Lattice Points: ____________________ Equation: ___________________________ p > 0, opens: _____________________ p < 0, opens: _____________________ Vertex: __________________________ Focus: __________________________ Directrix: ________________________ Lattice Points: ____________________

  6. Math III Warm Up 3/21/14 • What is the standard form equation of a parabola that opens down? • What do you need to find the focus of a parabola? • How do you find the directrix of a parabola? • What are lattice points?

  7. Ex 1: Identify the vertex, directrix, focus, and lattice points. Vertex: __________________________ Focus: __________________________ Directrix: ________________________ Lattice Points: ____________________ Equation: ___________________________ directrix

  8. Ex 1: Identify the vertex, directrix, focus, and lattice points. Vertex: __________________________ Focus: __________________________ Directrix: ________________________ Lattice Points: ____________________ Equation: ___________________________ focus
