**“Backwards” Parabolas**Today you will write the equation of a parabola given defining characteristics or the graph.**Parabolas**• Please pick up your clicker. Everything else should be cleared off of your table/desk. • This quiz is to be taken individually. • Good Luck **Point A is called the**• Vertex • Focus • Directrix • Axis of Symmetry • Latus Rectum**Point D is called the**• Vertex • Focus • Directrix • Axis of Symmetry • Latus Rectum**The green line is called the**• Vertex • Focus • Directrix • Axis of Symmetry • Latus Rectum**The yellow line is called the**• Vertex • Focus • Directrix • Axis of Symmetry • Latus Rectum**The red line is called the**• Vertex • Focus • Directrix • Axis of Symmetry • Latus Rectum**The distance between A and D and A and the red line is**called • a • h • k • p • d • f**The length of the green segment is**• 2a • 4a • 2p • 4p**Which variable would be squared in the equation for the**parabola below? • x • y**Find the equation of the parabola that satisfies the given**conditions. • Vertex is at (-2,3) • Focus is at (1,3)**Find the equation of the parabola that satisfies the given**conditions. • Focus is (-3, 4) • Directrix has equation x = - 5**Find the equation of the parabola that satisfies the given**conditions. • Vertex is at (0,0) • Symmetric about the y-axis • Passes through (3,3)**Find the equation of the parabola that satisfies the given**conditions.**Assignment**• A 3.2 Sect II & III
