Answer:

C. f(x)= log 1/x , x =/ 0.

Explanation:

Given : A science teacher wrote the table of values below.

To find : Which function models the data in the table.

Solution : We have given table with x and f(x ).

We can see from table if x =
(1)/(10) then f(x) =1

By logarithm rule : log (10) = 1 , log (100) = 2.

Substitute the values of x in f(x)=
log(1)/(x).

If x =
(1)/(10) .

f(x)=
log(1)/(((1)/(10))).

We can write it f(x) = log(10) = 1

If x =
(1)/(100) .

f(x)=
log(1)/(((1)/(100))).

We can write it f(x) = log(100) = 2

Therefore, C. f(x)= log 1/x , x =/ 0.
