Thus the axis of symmetry is #x=-1#

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

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#
