Select the vertex.

Does this graph have maximum or minimum value?

• maxima

• minima

• neither

• both

Define Vertex

• Where the parabola touches or intersects the x-axis

• The highest or lowest point on the graph

• Where parabola line touches or intersects the x- axis, also called the x-intercept

• A line that divides the graph into two equal parts. i.e. cuts the graph in half

Which function has an axis of symmetry of x = 0?

• 
• 
• 
• None of the above
