Vertex: The vertex is the highest or lowest point on the parabola, depending on its concavity. It represents the point where the parabola changes direction.
Axis of symmetry: The axis of symmetry is a vertical line passing through the vertex that divides the parabola into two mirror-image halves.
Concavity: Concavity indicates whether the parabola opens upward or downward. If it opens upward, the vertex is a minimum point; if downward, the vertex is a maximum point.
Range: The range of a quadratic function depends on the vertex and its concavity, representing all possible y-values the parabola can take.
The vertex is the highest or lowest point on the parabola, depending on whether the parabola opens downward or upward. The axis of symmetry is a vertical line that passes through this vertex, dividing the parabola into two mirror images. Concavity determines the direction the parabola opens: upward (minimum vertex) or downward (maximum vertex). The range of the quadratic function includes all y-values from the vertex's y-value to infinity or negative infinity, based on the parabola's concavity and position.
