##### 1 Answer

Vertex:

Axis of symmetry:

#### Explanation:

Given

**Part 1: The Vertex**

Convert into vertex form (

This is in vertex form with the vertex at

**Part 2: The Axis of Symmetry**

An parabolic equation in the form:

has a vertical axis (i.e.

Since the given

the axis of symmetry is
