we approximate the arbitrary base logarithm with a rational function, namely (ax+b)/(cx+d).
we choose a to be 2, b to be -2, c to be ln(a1), d to also be ln(a1)
a1 is the arbitrary base of the logarithm.
when we're done, we use the iteration formula for (ax+b)/(cx+d).
and we get this graph: https://www.desmos.com/calculator/x6malmxjzt
