Answer
$A$
Work Step by Step
Compare with figure 39.
This graph approaches the y-axis as x approaches zero from the right and
passes through (1,0), as a logarithmic function with base greater than 1 does.
It contains the point (3,1), so we conclude, because $\log_{3}3=1$,
that this is the graph of $ y=\log_{3}x\qquad$ ...choice A.
