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.
