MBF 3C 4.6 Graphing Quadratic Relations in Vertex Form Note 2011.notebook 1 December 02, 2011 Sep 158:07 PM • Graph quadratic relations in vertex form using the "step pattern". Learning Goals "By the end of today's class I will be able to..." Today's Agenda & Reminders "The answer to the problem you are solving is of far less importance than what you learn by solving it." • TEST moved to Monday!!! • Survey Assignments ready for pick up at back of classroom. • Mind Buster + HW Check • HW Q's? • Lesson: Graphing Quadratic Relations in Vertex Form Nov 27:32 PM M I N D B U S T E R Sec. 4.5 Interpret Graphs of Quadratic Relations 1. Answer the following about the graph to the right: a) Coordinates of the xintercepts b) Coordinates of the yintercept c) Axis of Symmetry d) Min/Max point e) Vertex 2. Find the yintercept for the following: a) y = 2x 2 + 4x + 8 b) y = 2(x 7) 2 +6 3. The equation representing your jump off a skateboard ramp is represented by h = 0.8t 2 +2 where t represents time in seconds and h represents your height above the ground in metres. a) Use transformations with a, h, and k to make a sketch of this graph. b) How high off the ground is the ramp that you jumped off of? c) How high will you be after 1 second? d) How long will you be in the air?
