Question

What is the domain of y= square root x+7+5?

Answer 1

x > -7

Explanation:

x is less than or equal to -7

Answer 2

Domain = {x /x ≥ -7}

Explanation:

The given function y =
`√(x+7)  + 5`

Inside the square, negative will not come.

First let's find the domain. x + 7 must be greater than or equal to 0.

x + 7 ≥ 0

Solving x, we get

x ≥ -7

Domain = {x /x ≥ -7}
