Key Concepts

Quadratic Functions

Quadratic functions are represented by equations of the form ax² + bx + c, and their graphs are parabolas. Understanding these functions involves analyzing how the coefficients affect the shape, orientation, and position of the parabola on the coordinate plane.

Vertex Form

The vertex form of a quadratic function is given by f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. This form makes it easier to identify the location of the vertex and understand how the graph is translated from the basic parabola f(x) = x².

Graph Transformations

Graph transformations include shifts, reflections, stretches, and compressions of the parent function f(x) = x². In the context of a quadratic function in vertex form, horizontal shifts and vertical shifts are key: the term (x + 4) indicates a shift to the left by 4 units when compared to the standard function.

Parabola Properties

Parabolas have important properties such as symmetry about a vertical line (the axis of symmetry), a vertex which represents the minimum or maximum point, and an opening direction that is determined by the sign of the leading coefficient. For an upward-opening parabola, the vertex is the minimum point of the graph.
