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.
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.
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).
3 days ago · The line that the object flips across is called the axis of symmetry (plural: axes of symmetry). An object may have 0, 1 or more than one axes of symmetry. An axis of symmetry is also sometimes called a line of symmetry. For example, the letters A and M, each have a vertical axis of symmetry, the letters E and K both have horizontal axes of ...
Therefore, the axis of symmetry is x = 3. Example 2: Find the axis of symmetry of the graph of y = 2x 2 + 8x – 3, using the formula. Solution: Given, y = 2x 2 + 8x – 3. Comparing the given equation with the standard form y = ax 2 + bx + c, a = 2, b = 8, c = -3. And the axis of symmetry is a vertical line; x = -b/2a. Substituting the values ...
