#1**+1 **

Domain

x cannot be any value < -5 because we would be taking the root of a negative number which isn't real

So....the domain is [-5, infinity )

The range is trickier

As small as the quantity under the radical can be is 0 [ when x = -5 ]

So 1/2 * 0 = 0

And as x grows larger than -5, the function keeps increasing to infinity

So....the range is [ 0, infinity )

The first answer is correct
