Answer
greater than 1
Work Step by Step
$\bf{\text{Solution Outline:}}$
The graph of $y=\log_b x$ goes up (from leftt to right) when the base, $b,$ is greater than $1.$ The graph goes down when the base is between $0$ to $1.$
$\bf{\text{Solution Details:}}$
Since the given logarithmic graph in Exercise $
1
,$ goes up (from left to right), then the base is $\text{
greater than 1
.}$
