  2. 4/18/16 Lesson 10 – 2 Day 1 Parabolas Algebra II

  3. Learning Objective • To graph parabolas • To write equation of parabolas

  4. Vocabulary Pg. 2 in packet Parabola – Set of all points in a plane that are the same distance from a fixed line (directrix) and a fixed point (focus) not on the line Focal Length (c) – distance between vertex and the focus Axis of Symmetry – cuts the parabola in half evenly

  5. To get information from an equation Pg. 2 in packet • Get into vertex form by completing the square • Determine which way the parabola opens •  Opens up/down •  Opens left/right • Find the Vertex (h, k) • Find c • Sketch a graphing labeling Vertex, Focus, and Directrix • Find Focus & Directrix using Vertex & c & graph to help you

  6. Parabola Equation Pg. 2 in packet • c = + opens up • c = – opens down • c = + opens right • c = – opens left

  7. Get into vertex form if it isn’t already. Find vertex, focus, and directrix. Sketch a graph. Pg. 2 in packet 1.  Directrix Vertex V(0, 0) F(0, –3) D: y = 3 Focus Opens down

  8. Get into vertex form if it isn’t already. Find vertex, focus, and directrix. Sketch a graph. Directrix 2. Focus Vertex F(-1.5, 0) V(–3, 0) Opens right D: x =
