Question

What is the domain of the function below?

Answer 1

`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
