Warm-up: 1) Find the standard form of the equation of the parabola given: the vertex is (3, 1) and focus is (5, 1) 2) Graph a sketch of (x – 3)2 = 16y
2
17) (x – 1)2 + 8(y + 2) = 0 or (x – 1)2 = -8(y + 2)
HW: pg. 372 (17, 18, 25, 26) Answers 17) (x – 1)2 + 8(y + 2) = 0 or (x – 1)2 = -8(y + 2) Vertex: (1, -2) Focus: (1, -4) Directrix: y = 0 V F
3
18) (x + 3) + (y – 2)2 = 0 or (y – 2)2 = -1(x + 3)
Vertex: (-3, 2) Focus: (-13/4, 2) Directrix: x = -11/12 F V
4
Vertex: (3, 2) Focus: (1, 2) (y – 2)2 = -8(x – 3) 26)Vertex: (-1, 2) Focus: (-1, 0) (x + 1)2 = -8(y – 2)
