2. Find the vertex.

9. See the first slide for descriptions and the second slide for how to find the vertex and x intercepts from intercept form.

30. Identify the x intercepts.

43. Start in vertex form using h ＝ 7 and k ＝ -3.

45. Start in intercept form using p ＝ 1 and q ＝ 9.

51. Start in vertex form using h ＝ -5.

52. The graph goes down until the axis of symmetry at x ＝ 4, and then turns back upward.

53. The minimum is k ＝ -3.

79. Use intercept form twice, with the same x intercepts but two different values of a.

82. See the last chapter 2 slide for the distance formula.
