Hi
f(x)= (x+1)^2 -3    |note use of ^(uppercase 6) for the squared term
Using the vertex form of a parabola, {{{y=a(x-h)^2 +k}}} where(h,k) is the vertex
  V(-1,-3)
{{{drawing(300,300,   -6, 6, -6, 6,  blue(line(-1,6,-1,-6))  , grid(1),
circle(-1, -3,0.3),
graph( 300, 300, -6, 6, -6, 6,0,(x+1)^2 -3  ))}}}
