Expert Answer:

The given function is
y = x2 + 4x + 6
   = (x + 2)2 + 2
The graph of the given function will be a parabola.
The parabola will open upward.
The least value of (x + 2)2 is zero and will be so when x = -2.
When x = -2, y = 2
The vertex is (-2, 2).
So, the graph of the given function is as follows.
