I'm trying to write a log function that intersects both the x and y axis at 100.
Through trial and error I have come up with this function, which is close to what I want. It appears to intersect the x axis at 99, and the y axis at 100.
I notice that for a function like:
- A controls the slope
- B shifts horizontally
- C shifts vertically
I'd like to learn how to write a log function like this such that the intersections of the axis are whatever arbitrary points I choose.
