Answer
$F$
Work Step by Step
Compare with figure 39.
This graph is a translation to the right, by 1 unit, of
a logarithmic function with base greater than 1.
So if a function f was such that $f(x)=\log_{a}x$,
then this graph represents $f(x-1)=\log_{a}(x-1)$
The best choice offered is: $F,\ y=\log_{3}(x-1)$
