I do not think this function has a vertex (considered as the highes or lowest point as in a parabola).

#### Explanation:

The square root, such as this one, has a graph that looks like a horizontal half parabola.

If you mean the hypotetical vertex of the complete parabola then you have that its coordinates are

The graph looks like this:

graph{sqrt(x+2) [-10, 10, -5, 5]}

As you can see you have only half parabola!
