Answer:

  (b)  y = (x +4)² -1

Step-by-step explanation:

The vertex form of the equation of a parabola is ...

  y = a(x -h)² +k . . . . . . . . . vertex (h, k); scale factor 'a'

The graph shows the vertex is (h, k) = (-4, -1) and a=1. Putting these values into the form, we have ...

  y =(x +4)² -1
