Answer 2

The domain is the interval [5,∞)

Explanation:

we have

`y = √(x-5)-1`

we know that

The radicand (number under a radical) must be greater than or equal to zero

so

`x-5\geq 0`

solve for x

Adds 5 both sides

`x-5+5\geq 0+5`

`x\geq 5`

therefore

The domain is the interval [5,∞)

All real numbers greater than or equal to 5
