These are always a little  difficult


The function (x + 2)^2   is a parabola that opens upward with a vertex of ( -2, 0)

All the graphs show this


The function   l x l  + 1   has a  y value of 

2 at x = -1

1 at x = 0

2 at x  = 1


This eliminates the first three graphs


So....by process of elimination, the last graph  must be the correct one....!!!


Do you see this OK ????
