Quadratic Vertex and Axis of Symmetry from Equation

The highest or lowest point on the parabola

• Parabola

• Domain

• Vertex

• Range

If "a" from y = ax² + bx + c is positive, then the vertex is the lowest point on the graph.

• Minimum

• Vertex

• Maximum

• Parabola

A vertical line that cuts the parabola into 2 symmetrical halves. This always goes through the vertex and ALWAYS begins with "x=" This is sometimes called the "line of symmetry".
