The vertex is at (

The axis of symmetry is

#### Explanation:

The standard form for the equation of a parabola is

Your equation is

So

**Vertex**

Since

The

Insert this value of

The vertex is at (

**Axis of symmetry**

The axis of symmetry must pass through the vertex, so

The axis of symmetry is
