1. Lesson 5.2 AIM: Review of Vertex and Axis of Symmetry

2. DO NOW: Find the Vertex and Axis of Symmetry Vertex: (1, -4) Axis of Symmetry: x = 1

3. Finding the vertex using the equation y = x 2 - 6x - 16 STEP 1: Determine “a”, “b”, and “c” a = 1 b = -6 c = -16

4. Finding the vertex using the equation y = x 2 - 6x - 16 STEP 2: Find the axis of symmetry using x = (-b/2a)

5. Finding the vertex using the equation y = x 2 - 6x - 16 STEP 3: Plug x value back into original equation to solve for y. x = 3 y = (3) 2 - 6(3) - 16 = 9 - 18 - 16 = -25 Vertex = (3, -25)
