The focus is a point on the axis of symmetry, but it is not on the actual parabola itself. This point is equal distance from any point on the parabola as that same point is from the directrix. Look at the image to see exactly how that works....
Theaxis of symmetry, which is the midline of the parabola, and thelatus rectum, which is perpendicular to the axis of symmetry, intersect at thefocus(see Figure 1) of the parabola. The distance between the focus and the vertex is called thefocal length,p. ...
In Graph 3, what is the equation of the axis of symmetry? Graph 3 It is the linex=−1 Axis of Symmetry Formula There are two different formulas that you can use to find the axis of symmetry. One formula works when the parabola's equation is invertex formand the other works when ...

The axis of symmetry is defined by x=−b2a.x=−b2a. If we use the quadratic formula, x=−b±√b2−4ac2a,x=−b±b2−4ac2a, to solve ax2+bx+c=0ax2+bx+c=0 for the x-intercepts, or zeros, we find the value of x halfway between them is...
The parabola's axis of symmetry (x = h) is a vertical line passing through the vertex, so as demonstrated above, this is x = 1. 4. Calculate the X-intercepts You can solve it using the quadratic formula: x = -b ±√(b² – 4ac) / (2a). Substitute the values of a, b and...
The equations of parabolas with vertex (0,0)(0,0) are y2=4pxy2=4px when the x-axis is the axis of symmetry and x2=4pyx2=4py when the y-axis is the axis of symmetry. These standard forms are given below, along with their general graphs and key features....
The vertex of a parabola is the highest or lowest point, also known as the maximum or minimum of aparabola. is the maximum or minimum value of the parabola (see picture below) is the turning point of the parabola the axis of symmetry intersects the vertex (see picture below)...
