What is the domain of the radical function shown on the graph? GRAPH IS IN THE PIC BELOW. A. all real numbers
B.
{x | x ≤ 0}
C.
{x | -10 < x < 10}
D.
{x | x ≥ -10}

Given:

The graph of a radical function.

To find:

The domain of the given radical function.

Solution:

We know that, domain is the set of input values or we can say domain is the set of x-values for which the function is defined.

From the given graph it is clear that, for each value of x there is a y-value. It means the function is defined for all real values of x. So,

Domain = Set of all real numbers.

Therefore, the correct option is A.
