Answer:
C
Step-by-step explanation:
Domain is all values left to right as long as the graph doesn't break or end. The domain includes all real numbers because they don't have an ending or starting point.
Range is all values down to up as long as the graph doesn't break or end. The graph goes from all real numbers up to 4, and the 4 is included since there isn't an open point. The graph ends at 4.
