Answer:
For the mathematical system that consists of the set of real numbers together with the operations of addition, subtraction, multiplication, and division, the resulting properties are called the properties of real numbers.
Closure Property of Addition also holds in real numbers: The sum of two real numbers is a real number.
multiplication pairs any two real numbers with a real number to become a product a×b
for all real numbers a and b, the difference denoted as a - b is defined by: a - b = a + (-b).
Hence we can also apply the BODMAS rule to the real numbers.

I believe that the answer to this is b
Answer:
x≥0 is correct inequality.
D is correct.
Step-by-step explanation:
We are given a function 
We need to find x where function is defined.
As we know negative inside the root not defined.
Inside the root value must be greater than equal to 0.
Here we have inside the root is x.
Therefore, x must be greater than equal to 0.
Inequality: x≥0
Please see attached graph for more clarification.
Hence, x≥0 is correct inequality.
