  1. Trash-ket Ball Quadratics

  2. Trash-ket Ball Rules • Each group member will have a letter, A, B, C, D • When the question comes up, all group members will complete the question, Ms. T will call a letter. If the group member whose letter is called gets the answer correct, he/she will be allowed to throw the trash-ket ball for points. • If the answer is wrong, the group has to help him/her fix it before they can get up to shoot. • *Make-up people, if you finish all your make-up work, you will be allowed to join a group. BUT it has to be done correctly!

  3. Question 1: No Calculator! • Find the AOS of the following equation: y = 3x2 – 12x + 2 x = 2

  4. Question 2: No Calculator! • Does the following equation have a maximum or a minimum? y = -x2 + 6x – 2 maximum

  5. Question 3: • Find the solutions for the following quadratic equation by factoring: y = 3x2 + 10x – 8 {-4, (2/3)}

  6. Question 4: • Find the Vertex of the following equation: y = 2x2 – 12x + 2 (3, -16)

  7. Question 5: No Calculator! • Describe the transformations that took place from the parent function y = x2 to the following function: y = -3x2 + 3 • Reflection over the x-axis • Vertically stretched by a factor of 3 • Translated up 3 units

  8. Question 6: No Calculator! • What are the Zeros of the graph? (-3, 0) and (-1, 0)

  9. Question 7: No Calculator! • What is the Vertex of the graph? (-2, -1)

  10. Question 8: No Calculator! • What is the y-intercept of the graph? (0, 3)

  11. Question 9: No Calculator! • Describe the transformations that took place from the parent function y = x2 to the following function: y = (3/4)x2 - 7 • Vertically shrunk by a factor of (3/4) • Translated down 7 units

  12. Question 10: No Calculator! • What is the y-intercept for the following quadratic equation: y = 3x2 + 10x – 8 (0,-8)

  13. Question 11: • Debo’s baby cousin Ray-Ray is stuck in a tree 33 feet above the ground. Debo throws a football at Ray-Ray trying to knock him out of the tree. The equation h = –16t2 + 40t + 6 gives the height of the football after t seconds with an initial velocity of 40 ft/sec. • How high can Debo throw the football? 31 feet

  14. Question 12: • Ralph hit a softball into the air with an initial upward velocity of 48 feet per second. The height h in feet of the ball above the ground can be modeled by h = –16t² + 48t + 3, where t is the time in seconds after Ralph hit the softball. • At what time will the softball hit the ground? 3.06 seconds
