Finding Quadratic Characteristics

What is the vertex?

• The line that cuts a parabola in half

• the highest or lowest point

• where the graph touches the x-axis

• where the graph touches the y-axis

What is the axis of symmetry?

• The line that cuts a parabola in half

• the highest or lowest point

• where the graph touches the x-axis

• where the graph touches the y-axis

What are the zeros?

• The line that cuts a parabola in half

• the highest or lowest point

• where the graph touches the x-axis

• where the graph touches the y-axis
