Examples
For instance, one may define the base b of a logarithm by : where b is a parameter that indicates which logarithmic function is being used.
Moreover, because the logarithmic function log(x) grows very slowly for large x, logarithmic scales are used to compress large-scale scientific data.
The function that assigns to y its logarithm is called logarithm function or logarithmic function (or just logarithm).
