Step-by-step explanation:

A. 356!

The correct answers are:

Question 1:  C. The domain of the graph is all real numbers less than or equal to 0. ; and Question #2:  C. The range of the function is all real numbers less than or equal to 0.

Explanation:

For Question #1:

We cannot use real numbers to take the square root of a negative number.  This means if we are to have a real number value for this, we can only use values of x that are negative; this will make it the square root of a "negative negative," which makes it the square root of a positive.  This means the domain, or list of all possible x values, would be real numbers less than or equal to 0.

For Question #2:

We can see in the graph that the domain, or set of x values, goes from 0 towards positive infinity.   We can also see that the range, or set of y values, starts at 0 and decreases; this means that the range is all real numbers less than or equal to 0.
