When the parabola opens either upwards or downwards, indicating a vertical axis of symmetry, the equation of the axis is a simple vertical line passing through the vertex. For a parabola with a vertex at `(h, k)` that opens upwards or downwards, the axis of symmetry equation is \( x = h \).

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...
Oct 8, 2024 · The axis of symmetry of a parabola is a vertical line that divides a parabola into two halves. This line passes through the vertex of the parabola, which is the highest or lowest point of the graph, depending on its orientation.
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.
Correct answer: xsymmetry = 3 2. Vertex: (3 2, −29 4) Explanation: The first step of the problem is to find the axis of symmetry using the following formula: xsymmetry = − b 2a. Where a and b are determined from the format for the equation of a parabola: y = ax2 + bx + c.
