X = − b 2a
- The axis of symmetry is defined by x = − b 2a. If we use the quadratic formula, to solve ax2 + bx + c = 0 for the x- intercepts, or zeros, we find the value of x halfway between them is always x = − b 2a, the equation for the axis of symmetry.

Sep 23, 2022 · A step-by-step guide to finding the axis of symmetry of quadratic functions. The axis of symmetry is a straight line that makes the shape of the object symmetrical. The axis of symmetry creates precise reflections on each of its sides. It can be horizontal, vertical, or lateral.
The axis of symmetry of a quadratic function is the vertical line that divides the parabola into two equal parts. Equation of the axis of symmetry. Let *f (x)=ax^2+bx+c* be the quadratic function, the axis of symmetry of the graph of this function has the equation: *x=\dfrac {-b} {2a}*
The axis of symmetry formula uses the standard form of the quadratic equation as well as the vertex form. The symmetry cuts any geometric shape into two equal halves. The axis of symmetry formula is given as, for a quadratic equation with standard form as y = ax 2 + bx + c, is: x = -b/2a.
Aug 3, 2023 · The axis of symmetry is best studied in a parabola, while graphing a quadratic function. Thus, the axis of symmetry of a parabola is the line about which a parabola is symmetric. It always passes through its vertex. The x -coordinate of the vertex is the equation of the parabola’s axis of symmetry. Axis of Symmetry.
Feb 1, 2024 · The axis of symmetry, \ (x=h\) is the \ ( \underline {\textrm {equation}} \) of the vertical line through the vertex. The maximum or minimum value depends on the \ (y\)-coordinate, \ (k\), of the vertex and the orientation of the parabola.
