Question

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

Answer 1

The answer is x≥0 because all the x-values that exist on this curve are more than or equal to 0; a negative x-value will never exist on this curve.

Answer 2

Option d

Explanation:

Given is a graph of a square root function.

From the graph we find that x takes only values >or equal to 0 and y never takes positive values but negative starting from -1

Hence the possible function may be having square root of x

because defined only for positive x.

Possible function may be

`y=-√(x) -1`

Domain is set of all non negative real numbers

i.e. x≥0
