  14. Factored form of a quadratic • Draw

  15. Find the intercepts by putting x = 0 and y = 0 • Y-intercept is (0, -15) • X-intercepts are (5, 0) and (-3, 0) • The line of symmetry is half way between these points at x = 1 and y = -16

  16. Find the intercepts by putting x = 0 and y = 0 • Y-intercept is (0, -15) • X-intercepts are (5, 0) and (-3, 0) • The line of symmetry is half way between these points at x = 1 and y = -16

  17. Sketch these graphs

  18. Note that this is just • Moved down 3

  19. Sketch the following graphs with their axis of symmetry and give the coordinates of the vertex

  20. Vertex (3.5, -6.25)

  21. Vertex (-4, -36)

  22. Vertex (1, -36)

  23. Vertex (1.5, -2.25)

  24. A is (0, -6) or if the diagram is to scale (1, -4)

  25. B (-3, 0)

  26. C (2, 0)

  27. D (-0.5, 0)

  28. E (-0.5, -6.25)

  29. A stone is fired from a catapult. The height gained by the stone is given by the equation • h= height of the stone • t = time in seconds • At what times is the stone at a height of 25 metres?

  30. Use the calculator to solve and round to appropriate level:

  31. What is the stone’s height after 2.5 seconds?

  32. Use the calculator to solve and round to appropriate level:
