**Axis of Symmetry:**

**Vertex:**

#### Explanation:

The first thing you must do, is convert this equation to vertex form

**Converting to Vertex Form ( #y=a(x-h)^2+k#)**

**Axis of Symmetry**

The axis of symmetry is

Therefore, the axis of symmetry is:

**Vertex**

The vertex is

Therefore, the vertex is:
