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.
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).
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.
Every parabola has an axis of symmetry which is the line that divides the graph into two perfect halves. On this page, we will practice drawing the axis on a graph, learning the formula, stating the equation of the axis of symmetry when we know the parabola's equation
For parabolas, the axis of symmetry is the line that passes through the vertex and divides the parabola into two equal halves. This axis is crucial for understanding the properties of parabolas, such as the location of the focus and the directrix. Similarly, for ellipses and hyperbolas, the axis of symmetry represents the major and minor axes ...
