Calculate y after assigning a value to x

Explanation:

If x is -2, your function y=0
If x is -1, your function y=sqrt1
If x is zero, your function y=sqrt2
If x is 1, your function y=sqrt3
If x is 2, your function y=sqrt4=2
Your function is not defined if x is less than -2.

You can graph now:

graph{sqrt(x+2) [-5.75, 14.25, -5.69, 4.31]}
