- 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.

The vertex can be thought of as the center of a parabola. Begin by finding the axis of symmetry with the following formula: x = −b 2a. Where b and a come from the standard equation of a parabola: y = ax2 + bx + c. So given our parabola. y = 5x2 − 25x − 10. x = − − 25 2 ⋅ 5 = 25 10 = 2.5.
The Vertex formula of a parabola is used to find the coordinates of the point where the parabola crosses its axis of symmetry. The vertex is the point (h,k). As we know the standard equation of a parabola is y = ax 2 +bx+c.
Finding Vertex from Standard Form. The x-coordinate of the vertex can be found by the formula −b 2a − b 2 a, and to get the y value of the vertex, just substitute −b 2a − b 2 a, into the the equqation as shown in the diagram and example below:
There are two different formulas that you can use to find the axis of symmetry. One formula works when the parabola's equation is in vertex form and the other works when the parabola's equation is in standard form .

Oct 3, 2018 · Find the line of symmetry of y = x2 + 2 x with 3 steps. Find the vertex, which is the lowest or highest point of a parabola. Hint: The line of symmetry touches the parabola at the vertex. (-1,-1) Hint: The line of symmetry (for any quadratic function) is always x = n because it is always a vertical line.
