Key Concepts

Extremum (Maximum or Minimum) of a Quadratic

A quadratic function will have either a maximum or minimum value at its vertex, depending on the sign of the leading coefficient a. If a is positive, the parabola opens upward, and the vertex represents the minimum value. Conversely, if a is negative, the parabola opens downward, and the vertex represents the maximum value.

Axis of Symmetry

The axis of symmetry of a quadratic function is a vertical line that passes through the vertex of the parabola, effectively dividing the graph into two mirror-image halves. The equation for the axis of symmetry is x = -b/(2a), which directly relates to the vertex's x-coordinate.

Vertex of a Quadratic Function

The vertex of a quadratic function is the highest or lowest point on its graph, depending on whether the parabola opens downwards or upwards. It is found using the formula (-b/(2a), f(-b/(2a))) and represents the point of maximum or minimum value of the function.

Quadratic Functions

Quadratic functions are polynomial functions of degree two, typically expressed in the standard form ax² + bx + c, where a, b, and c are constants. These functions represent parabolic graphs that can open upwards or downwards depending on the sign of the coefficient a.
