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. Note: For a parabola facing upward or downward, the axis of symmetry is a vertical line (one is shown above).
Aug 3, 2023 · How to Find the Axis of Symmetry on a Graph. For a parabola the axis of symmetry always passes through the vertex. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form y = ax 2 + bx + c, the axis of symmetry is x = -b/2a.
Oct 6, 2021 · Lastly, the line of symmetry 12 (also called the axis of symmetry 13) is the vertical line through the vertex, about which the parabola is symmetric. Figure \(\PageIndex{2}\) For any parabola, we will find the vertex and \(y\)-intercept.
Jun 4, 2023 · Each of the constants in the vertex form of the quadratic function plays a role. As you will soon see, the constant a controls the scaling (stretching or compressing of the parabola), the constant h controls a horizontal shift and placement of the axis of symmetry, and the constant k controls the vertical shift.
