      • Vertex is where the axis of symmetry intersects the parabola. This vertex serves as the focal point for determining the equation of the axis of symmetry. 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.

  1. The vertex is the point where the axis of symmetry intersects the parabola. This is the key point to determine its equation. If the parabola opens up or down, the axis of symmetry is vertical and in this case, its equation is the vertical line that passes through its vertex.

  2. 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.

  3. 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. Note: For a parabola facing upward or downward, the axis of symmetry is a vertical line (one is shown above).

  4. Introduction. The axis of symmetry is a line that divides a shape or function into two identical halves as if folding it along that line. It's crucial in quadratic functions, where it's a vertical line passing through the vertex of the parabola. “Axis of symmetry” is also called “line of symmetry”.

  5. Jun 4, 2023 · The axis of symmetry passes through the vertex (−2, 3) in Figure \(\PageIndex{13}\) and has equation x = −2. Note that the right half of the parabola is a mirror image of its left half across this axis of symmetry.

  6. Feb 13, 2022 · For a parabola with equation y = ax2 + bx + c: The axis of symmetry of a parabola is the line x= − b 2a. The vertex is on the axis of symmetry, so its x -coordinate is − b 2a. To find the y -coordinate of the vertex, we substitute x= − b 2a into the quadratic equation.

  7. The Axis of symmetry is generally the axis of the parabola and it cut the parabola at its vertex. The axis of symmetry of a standard parabola having the equation y 2 = 4ax is the x-axis.The axis of symmetry of parabola divides the parable into two rectangular arcs.
