Answer:
B. Domain: {1, 2, 3, 4, 5, ...}; Range: {2, 6, 18, 54, 162, ...}
Step-by-step explanation:
2, 6, 18, 54, 162
This is a geometric sequence because it is increasing by multiplication. The common ration of the sequence is *3.
Our sequence values will serve as the y-values, or the range, and our x-values will be the term number.
Domain, or x-values: {1, 2, 3, 4, 5, ...}
Range, or y-values: {2, 6, 18, 54, 162, ...}
It is not A or D because we can't have negative term values. "All real numbers" implies all positive and negative integers.
The range also cannot be all real numbers for the same reason.
