Axis of symmetry formula for a parabola is, x = -b/2a. Let us derive the equation of the axis of symmetry. The quadratic equation of a parabola is, y = ax 2 + bx + c (up/down parabola). The constant term 'c' does not affect the parabola.Therefore, let us consider, y = ax 2 + bx.
Aug 3, 2023 · The vertex form of a quadratic equation is y = a (x – h) 2 + k, Equation of axis of symmetry is, x = h, here (h, k) = vertex of the parabola. We obtain the vertex of the function (x, y) by substituting the value of x in the standard form of the equation and get the value of y. Let us solve some examples involving the above formulas and concepts.
symmetry, in biology, the repetition of the parts in an animal or plant in an orderly fashion. Specifically, symmetry refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis. With the exception of radial symmetry, external form has little ...

The axis of symmetry is a fundamental concept in both geometry and algebra. It refers to a line that divides a figure or graph into two identical halves, each being the mirror image of the other. This line can be vertical, horizontal, or even diagonal, depending on the context and the shape being considered.
Since the parabola is symmetrical around its vertex, the axis of symmetry is a vertical line passing through the vertex. Therefore, the axis of symmetry is x = 1. Example 3. Write the equation for the axis of symmetry. y = x 2 + 8 x + 11. Solution: The vertex of the parabola is at (− 4, − 5).
Jan 3, 2024 · The Axis of Symmetry, a term that can often be heard in Geometry and Algebra, is a line that divides a shape or a graph into two mirror-image halves. Each point on one side of the axis has an identical ‘twin’ on the other side. For a simple visual understanding, think of the line that runs through the center of a perfectly round apple or ...
