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.
axis of symmetry. a vertical line drawn through the vertex of a parabola around which the parabola is symmetric; it is defined by x=−\dfrac {b} {2a}. general form of a quadratic function. the function that describes a parabola, written in the form f (x)=ax^2+bx+c, where a,b, and c are real numbers and a≠0.
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.
f(x) = ax2 + bx + c. where a, b, and c are real numbers and a ≠ 0. If a> 0, the parabola opens upward. If a <0, the parabola opens downward. We can use the general form of a parabola to find the equation for the axis of symmetry. The axis of symmetry is defined by x = − b 2a.
