Answer:
C
Step-by-step explanation:
The red portion shows all numbers GREATER THAN or EQUAL TO 0.
So that would be x ≥ 0
Looking at the answer choices, there is no "x", rather "√x"
To make it "x", we need to square both sides and the option C wouldn't make a difference. Shown below:
[tex]\sqrt{x} >0\\(\sqrt{x} )^2>0^2\\x>0[/tex]
Option C is right.
