To find the axis of symmetry start with the vertex. The vertex of this parabola is (3, 1). The axis of symmetry is at *y* = *v*, so for this example, it is at *y* = 1.

For the equation given, *a* = 1/8, and so the focal distance is 2. Add this value to *h* to find the focus: (3 + 2, 1) or (5, 1).

To find the directrix, subtract the focal distance from Step 2 from *h* to find the equation of the directrix. Because this is a horizontal parabola and the axis of symmetry is horizontal, the directrix will be vertical. The equation of the directrix is *x* = 3 – 2 or *x* = 1.
