  1. Do Now: Match each equation with its graph

  2. Review Chapter 2

  3. Write an Equation that has the following properties • Vertex: (10,-4); passes through (1,12) • Points: (-1,0), (5,3), (7,0)

  4. Passes through (4,3); x-intercepts of -1 and 5

  5. Let the graph of g be a translation 2 units left and 1 unit down, followed by a reflection in the y-axis of the graph of f(x) = (2x + 1)2 – 4 Let g be a horizontal shrink by a factor of 1/3 followed by a translation 2 units up and 4 units left of the graph of f(x) = (3x – 2)2 + 5

  6. Graph: y = 3x2 – 6x + 4

  7. Graph: y = -(x +3)2 + 5

  8. Graph: y = 2(x+3)(x-1)

  9. Explain why a quadratic function models the data. Then find the model. 1) 2)

  10. An object is launched directly overhead at 36 meters per second. The height (in meters) of the object is given by h(t) = -16t2 + 36t + 5 where t is the time (in seconds) since the object was launched. How high does it get? When is it at its highest?

  11. Closing • Make a list of everything you need to study for the test tomorrow.
