Since is in vertex form where a is the stretch/compression factor and (h,k) is the vertex, this means that h=-2 and k=0 (note: really looks like )

So the vertex is (-2,0)

Also, the line of symmetry is simply the equation . So in this case the line of symmetry is

If we graph, we can visually verify our answer.

Graph of with a vertex of (-2,0) and the line of symmetry of
