Define Maximum

• The highest x-value on the graph

• The highest y-value on the graph

• The lowest y-value on the graph

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

In the vertex (3, -6), the 3 represents:

• maximum value

• axis of symmetry

• minimum value

• y-intercept
