What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola, represented as a coordinate (h, k) in the vertex form of a quadratic equation: y = a(x-h)^2 + k.

What is the maximum value of a quadratic function?

Back

The maximum value occurs at the vertex of the parabola when it opens downwards. It is the y-coordinate of the vertex.

What are the decreasing intervals of a quadratic function?

Back

The decreasing intervals are the ranges of x-values where the function's output (y-value) is decreasing. For example, if the vertex is at (0, 2) and the parabola opens upwards, the decreasing interval is from (-∞, 0].
