The equation of the function represented by the graph is

How to determine the equation of the function
From the question, we have the following parameters that can be used in our computation:
The graph
A logarithmic function is represented as

Where, b is the base of the function
Using the point (6, 1), we have

So, we have

Evaluate
b = 6
Recall that

So, we have

Hence, the equation of the function is
