Identify the domain of the function shown in the graph.

The domain of the function is:

                     Option: C

         C.   x is all real numbers.

We are given a graph as a straight horizontal line.

Also, the line extends to infinity in both the direction.

This means that the domain of the function is all the real numbers.

Since, the function takes a constant value for all the real numbers.

Hence, the range of the function is the fixed constant i.e. 1.5

Hence, the function is a constant function as we know that the constant function is defined all over the real line.

        Hence, the answer is:

         C.   x is all real numbers.
