Question

How do you graph `y=log_7x`?

Answer 1

You may convert to base 10 or base e as follows:
`y = (1/log_10(7))log_10(x)`
`y = (1/ln(7))ln(x)`
Then it is a matter of plotting points.

Explanation:

Here is a graph

The red line is the logarithm base 7
The blue line is the logarithm base e.
I was going to show base 10 but is was so close to the base 7 curve that it made the graph confusing.
