x

To get the domain of a function, the function must output a number that is not a division by zero or a square root of a negative number.

Also the graphs seemed to be like
√(x +2) -1.

If we let your graph be y


y = √(x +2) -1 This equation must be the graph.

If a function shouldn't output a square root of a negative number so it must be
x +2 ≥ 0 so that there will be no negative number under the radical sign.


x +2 ≥ 0 \\ x ≥ -2

Also we can see that the graph has no y's for x's lesser than -2
