Axis of symmetry:

Vertex:

#### Explanation:

Note that any parabolic equation of the general form:

has a vertical axis of symmetry.

is in this general form.

Further, it can be re-written as

which is the vertex form with a vertex at

Its (vertical) axis of symmetry (i.e.

therefore, the axis of symetry is
