This quadratic function represents all points on a parabolic curve where y equals x squared. It's an example of a polynomial function.
Parabola: A U-shaped curve formed by plotting points that satisfy an equation such as f(x) = ax^2 + bx + c.
Vertex: The highest or lowest point on a parabola, also known as the maximum or minimum point.
Axis of symmetry: A vertical line passing through the vertex that divides the parabola into two symmetrical halves.
