Tema [17]

Answer:

<u>Option 3:  0 ≤ x ≤ ∞ </u>

Step-by-step explanation:

The domain of a function is the set of all possible x values for the function.

The given function is y = √x

The domain for the square root function should be : x ≥ 0

So, the domain = [0,∞)

Or, it can be written as inequality

So, 0 ≤ x ≤ ∞

So, the answer is option 3.
