Concept 3: Quadratics (Graphing)

The maximum or minimum of a parabola is the vertex of the graph. It is either the highest or the lowest point of the graph. If 'a' is positive as in the example above then the parabola opens upward and has a minimum vertex. If 'a' is negative then the parabola will open downwards as in the second example above in the KEY Concepts and will have a maximum vertex.

[|Glencoe Tutor] Use the axis of symmetry formula (above) to find 'x', plug 'x' back into the equation to find 'y'. Once you know what (x, y) then you know what the coordinate of the vertex is. Determine whether the vertex is a maximum or a minimum by looking at the value of 'a', since a = 1 (positive) then, the vertex (1,2) is a minimum and the graph goes upward (smilie face) Concept 3: Quadratics (Graphing)
