What is the vertex of a parabola?
The vertex of a parabola is the point where the parabola reaches its minimum or maximum value. For a parabola in the form y = ax^2 + bx + c, the vertex is given by the coordinates (-b/2a, f(-b/2a)), where f(x) represents the quadratic function.
The x-coordinate of the vertex is found using the formula, and substituting this x-value back into the equation provides the corresponding y-coordinate. The vertex is a critical point on the parabola, representing either the minimum or maximum point depending on the direction of its opening.

The vertex of a parabola is the point where the parabola reaches its minimum or maximum value. For a parabola in the form y = ax^2 + bx + c, the vertex is given by the coordinates (-b/2a, f(-b/2a)), where f(x) represents the quadratic function.
To find the vertex of a parabola in standard form (y = ax^2 + bx + c), use the formula x = -b/2a to find the x-coordinate of the vertex. Substitute this x-value back into the equation to find the corresponding y-coordinate.
Yes, if the parabola is in vertex form (y = a(x-h)^2 + k), the coordinates of the vertex are (h, k). The values of h and k directly give the x and y coordinates of the vertex.
The vertex of a parabola represents either the minimum or maximum point of the curve, depending on the direction of its opening. It is a critical point in understanding the behavior and characteristics of the parabolic curve.
Yes, an alternative method for finding the vertex involves completing the square. By transforming the quadratic equation into vertex form, the coordinates of the vertex become readily apparent, simplifying the process of finding this key point on the parabola.
