Key Concepts

Axis of Symmetry

The axis of symmetry is a vertical line that passes through the vertex of the parabola. This line divides the parabola into two congruent halves and can be expressed by the equation x = h when the quadratic is in vertex form.

X-Intercepts

X-intercepts are the points where the graph of the quadratic function crosses the x-axis (when f(x) = 0). They are found by solving the quadratic equation and represent the function's roots.

Vertex

The vertex of a parabola is the highest or lowest point of the graph, depending on whether it opens downward or upward. It represents the optimal value of the quadratic function and is the point of symmetry for the graph.

Vertex Form

The vertex form of a quadratic function is expressed as f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. This form makes it easier to determine the vertex and the axis of symmetry of the parabola.

Standard Form

The standard form of a quadratic function is f(x) = ax² + bx + c. This form is useful for identifying the coefficients that influence the shape and position of the parabola and can be converted to vertex form for further analysis.

Quadratic Function

A quadratic function is a second-degree polynomial function characterized by its highest exponent of 2. It's commonly written as f(x) = ax² + bx + c, and its graph is a parabola that opens upward if a > 0 or downward if a < 0.
