Answer:
Domain = {x /x ≥ -7}
Step-by-step explanation:
The given function y = ![\sqrt{x+7} + 5](https://tex.z-dn.net/?f=%5Csqrt%7Bx%2B7%7D%20%20%2B%205)
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}
Hope this will help you.
