Question

determine the domain and range of the following function. Record your answers in set notation. Can someone explain this to me? I can't understand any of it.

Answer 1

The answer is D.

Explanation:

The domain are the x-values and the range are the y-values. The open circle on the graph is stating that that specific point is not included in the line, so that means that the point (-2,-5) is not included. In words, the answer means the domain or x=all real numbers not including -2 and the range or y=all real numbers not including -5. Hope it helps
