How to Find the Axis of Symmetry The quadratic equation also defines an axis of symmetry, which is a vertical line at the center of the parabola passing through its vertex. The formula to calculate the axis of symmetry is: x=−b2ax=2a−b Thus, the x coordinate of the axis of sym...
The vertex of a quadratic function (which is in U shape) is where the function has a maximum value or a minimum value. The axis of symmetry of the quadratic function intersects the function (parabola) at the vertex.Quadratic Functions Formula...
If our function is in the form of y=ax² + bx + c then vertex of the parabola The line passing through vertex and parallel to the y-axis is called the axis of symmetry. The parabolic graph of a quadratic function is symmetrical about axis of symmetry. f(x) has a minimum value at...

Quadratic equations are used to find the zeroes of the parabola and its axis of symmetry. There are many real-world applications of quadratic equations. They can be used in running time problems to evaluate the speed, distance or time while traveling by car, train or plane. Quadratic equations...
Axis of symmetryThe quadratic formula learned by generations of math students is difficult to remember, but it can be used to solve quadratic equations where y = 0. Solving the equation gives the two points where the parabola crosses the x-axis (the two values of x when y = 0):What ...
