Key Concepts

Quadratic Functions in Vertex Form

A quadratic function written in vertex form, y = a(x-h)² + k, clearly displays the vertex of the parabola and simplifies the process of graphing by showing horizontal and vertical shifts, reflections, and vertical stretches or compressions. This form makes it easier to understand how the graph of the function is derived from the basic shape of the quadratic function.

Vertex of a Parabola

The vertex of a parabola, given by the point (h, k) from the vertex form of the quadratic function, represents the maximum or minimum point of the graph. Identifying the vertex is crucial because it provides a reference point around which the parabola is symmetric and guides the graphing process by indicating the point where the function changes direction.

Graph Transformations

Graph transformations involve shifting, reflecting, stretching, or compressing the basic graph of a function according to changes in its equation. In the context of quadratic functions in vertex form, transformations include horizontal and vertical translations determined by the values of h and k, as well as vertical reflections and scaling due to the coefficient a, which affects the direction and width of the parabola.
