Answer:
Table B
Step-by-step explanation:
The missing tables are shown in the attachment.
We want to select which table represents an exponential function of the form [tex]y=b^x[/tex] when 0 < b < 1.
For an exponential function in the form [tex]y=b^x[/tex] with 0 < b < 1 the output values approaches zero as x-values grows bigger and bigger positively.
In other words, the output values are  decreasing exponentially, as x-increases as shown in the output values of table B
[tex]27\to9\to3\to1\to\frac{1}{3}\to\frac{1}{9} \to\frac{1}{27}[/tex]
The only table that represents such a function is table B.
