What is the domain of the square root function graphed below?

Answer:
Option (4)
Step-by-step explanation:
Domain of a function is a set of x-values (Input values) of the function.
For the given graph of square root function,
x - values starts from x = 0 and tends to x = ∞
Therefore, domain of the function will be,
x ≥ 0
Option (4) will be the correct option.
