Question

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

Answer 1

Option D is correct.

Explanation:

Given: A graph.

We know that The domain of a function is the complete set of possible values of the independent variable.

From given graph x is independent variable.

Generally Domain for the Square root function is all non negative real numbers.

So, from given graph and general domain.

Domain of given graph = x ≥ 0

Therefore, Option D is correct.

Answer 2

The graph shows that x never becomes < 0. In other words the point (-1,0) is not part of the graph. So D is your only answer.
