1. Warm Up

2. L5-2 Obj: Students will be able to graph quadratic functions
L5-2 Obj: Students will be able to graph quadratic functions. Students will find the vertex, identify the vertex as the max or the min, and find the axis of symmetry.

3. Properties of Parabolas1 3
Graph y = x2 + 1.

4. Graph y = x2 + x + 3. Label the vertex and axis of symmetry.
Properties of Parabolas 1 2
Graph y = x2 + x + 3. Label the vertex and axis of symmetry.

5. 1. Graph y = 2x² - 4

6. 2. Graph y = -x² + 4x + 2

7. Since a < 0, the graph of the function opens down, and the vertex represents the maximum value. Find the coordinates of the vertex.

8. 3. Find the minimum value
y = 2x² + 8x - 1
