Therefore, the axis of symmetry is \( x = 3 \). Example `5`. The roots of a parabola are `(-7,0)` and `(3,0)`. Find the axis of symmetry for this parabola. Solution: We know the axis of symmetry passes exactly through the middle of its `2` `x`-intercepts. We can calculate the average of the two `x`-intercepts to find the `x`-coordinate of the ...

The axis of symmetry is an imaginary line that divides a figure into two identical parts such that each part is a mirror reflection of one another. When the figure is folded along the axis of symmetry, the two identical parts superimpose. A parabolahas one line of symmetry. The axis of the symmetry is the straight line that divides a parabola into ...
The quadratic equation in standard formis, y = ax2+ b x+c where a, b, and c are real numbers. Here, the axis of symmetry formula is: x = - b/2a.
The quadratic equation in vertex form is, y = a (x-h)2 + k where (h, k) is the vertex of the parabola. Here, the axis of symmetry formula is x = h. The axis of symmetry always passes through the vertex of the parabola. Thus identification of the vertex helps us to calculate the position of the axis of symmetry. Axis of symmetry formula for a parabo...
Sep 10, 2018 · The symmetry is common for figures where you have to divide the shape in equal parts. It could be lines of symmetry, axis of symmetry or more. In this post, our focus in axis of symmetry in the x-y coordinate plane. Consider the given image whose axis of symmetry lies over y-axis. The vertex of this parabola is an ordered pair (0, 0).
Aug 3, 2023 · A circle has infinite lines of symmetry; A parallelogram has no line of symmetry; A regular polygon with ‘n’ sides has ‘n’ axes of symmetry; In Parabola. 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.
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 ...
