Write the equation of a parabola with a vertex of (2, -1) and which opens downward

  1. Write the equation of a parabola with a vertex of (2, -1) and which opens downward.
  2.  List three points you might test to find the solution of (x + 3)(x - 5) < 0. Explain why you chose these points.
  3.  Write a system of equations with one linear equation and one quadratic equation for which (2, 6) is a solution.
  4. Use page 306 to Explain how the graph of y = x2 can be used to graph any quadratic function. Include a description of the effects produced by changing a, h, and k in the equation y = a(x - h)2 + k, and a comparison of the graph of y = x2 and the graph of y = a(x - h)2 + k using values of your own choosing for a, h, and k.
  5.  Use the information on page 314 to explain how you can find the time a trampolinist spends above a certain height. Include a quadratic inequality that describes the time the performer spends more than 10 feet above the ground, and two approaches to solving this quadratic inequality.

    ps: Find pages 306 and 314 attached below
