April 24, 2014 April 24, 2014 Presentation Transcript

  • Today:
  • Warm-Up/Final Exam Review: 1. Name the x and y intercepts, then graph the line using graph paper. y intercept is 3; x intercept is 18
  • 3. What are the three methods for solving systems of equations? A. Graphing B. Substitution C. Elimination 4. Solve the following systems of equations Warm-Up/Final Exam Review:
  • Quadratic Exam Review I. The Discriminant II. Quadratic Applications III. Questions on any Quadratic Topic IV. Class Work
  • The Discriminant The discriminant is the part of the quadratic formula inside the radicand. The discriminant tells you the number of solutions and should be computed first. If the discriminant is: = 0; 1 solution > 0; 2 solutions < 0 no solutions y = 4x2 – 17x – 15 How many times does the graph cross the x axis?
  • w = 5, l = 15 Quadratic Applications
  • Quadratic Applications
  • A batter smashed a fastball high into the gap between left and center fields. The path of the ball is shown by the equation y = -.2x2 + x. This allowed the center fielder enough time to run and make the catch. How high was the ball hit? -1/.02 = 50; x = 50 Substitute 50 for x; y = Quadratic Applications
  • Class Work:
