The vertex of a parabola is the place where it turns; hence, it is also called the turning point. If the quadratic function is in vertex form, the vertex is (h, k). Using the method of completing the square, one can turn the standard form = + + into
Given a quadratic polynomial of the form + the numbers h and k may be interpreted as the Cartesian coordinates of the vertex (or stationary point) of the parabola. That is, h is the x -coordinate of the axis of symmetry (i.e. the axis of symmetry has equation x = h ), and k is the minimum value (or maximum value, if a < 0) of the quadratic ...
In the theory of quadratic forms, the parabola is the graph of the quadratic form x 2 (or other scalings), while the elliptic paraboloid is the graph of the positive-definite quadratic form x 2 + y 2 (or scalings), and the hyperbolic paraboloid is the graph of the indefinite quadratic form x 2 − y 2. Generalizations to more variables yield ...
If a < 0, the parabola has a maximum point and opens downward. The extreme point of the parabola, whether minimum or maximum, corresponds to its vertex. The x-coordinate of the vertex will be located at =, and the y-coordinate of the vertex may be found by substituting this x-value into the function.
On a parabola, the sole vertex lies on the axis of symmetry and in a quadratic of the form: a x 2 + b x + c {\displaystyle ax^{2}+bx+c\,\!} it can be found by completing the square or by differentiation . [ 2 ]
Jimmy Butler #22 of the Miami Heat looks on during the game against the Toronto Raptors on December 1, 2024 at the Scotiabank Arena in Toronto, Ontario, Canada.
In terms of coordinate geometry, an axis-aligned parabola is a curve whose (,) -coordinates are the graph of a second-degree polynomial, of the form = + + , where , , and are real-valued constant coefficients with .
