Answer:
D. The data represent an exponential function because there is a common ratio of 1/3.
Step-by-step explanation:
To find a common ratio, find out what the first "y" must be multiplied by to get to the next "y."
162 = 54x
162 ÷ 54 = 3
However, the common ratio is not 3 because the y values are decreasing. The common ratio is 1/3 because 162 × 1/3 = 54.
I hope this helps :))
