Thus the axis of symmetry is x=-1

Vertex ->(x,y)=(-1,0)

Explanation:

This is the vertex form of a quadratic.

Write as

y=1(x+color(red)(1))^2+color(blue)(0)

x_("vertex") = (-1)xxcolor(red)(+1)=color(purple)(-1)

Vertex ->(x,y)=(color(purple)(-1),color(blue)(0))

Thus the axis of symmetry is x=-1
