Question

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

Answer 1

Answer:

Domain = {x /x ≥ -7}

Step-by-step explanation:

The given function y = $\sqrt{x+7} + 5$

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}

Hope this will help you.
