Question

On a coordinate plane, 5 points are plotted. The points are (1, 1), (2, 3), (3, 9), (4, 27), (5, 81).
Use the graph to answer the questions.



The domain of the sequence is the set of
.

The common ratio is
.

The explicit formula for the sequence is

f(x) =
(
)x − 1.

Answer 1

- The domain of the sequence is the set {1, 2, 3, 4, 5}.
- The common ratio is 3.
- The explicit formula is f(x) = 3^{x−1}.
