1. Objective: Students will be able to 1)Find the axis of symmetry 2)Find the vertex 3)Graph a quadratic formula using a table of values

2. The graph of a quadratic equation is a parabola. the graph opens upwardthe graph opens downward

3. Vertex: the turning point of the parabola Axis of Symmetry: The vertical line that passes through the vertex and divides the parabola into two symmetric parts.
