Question

What are the domain and range of the function {(2, 0), (4, –2), (8, –2), (1, 6), (–5, 0)}?	
 
 A.
Domain: {2, 4, 8, 1, –5}; Range: {0, –2, 6}
 
 B.
Domain: {2, –2}; Range: {4, 1, 8, –5}
 
 C.
Domain: {2, 4, 8, 6, 0}; Range: {0, –2, 6}
 
 D.
Domain: {0, –2, 6}; Range: {2, 4, 8, 1, –5}

anonymous · Answer

Since the smallest and largest x values are -5 and 8 respectively, the domain is [-5, 8]

Since the smallest and largest y values are -2 and 6 respectively, the range is [-2, 6]

Does that help?
