Question

The domain of y=sqrt x-5-1 is

Answer 1

Answer:

The domain is the interval [5,∞)

Step-by-step explanation:

we have

$y = \sqrt{x-5}-1$

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
