Question

What is the domain of the function y=sqrt x+6-7

Answer 1

I hope this helps you



x+6>=0


x>= -6

Answer 2

we have

$y=\sqrt{x+6} -7$

we know that

The radicand  of the function must be greater than or equal to zero

so

$x+6 \geq 0$

$x\geq-6$

the solution is the interval---------> [-6,∞)

therefore

the answer is

The domain are all values of x  greater than or equal to minus six
