Increasing Real Function: Also known as

Some sources refer to an increasing (real) function as a non-decreasing (real) function, and use the term increasing real function for what on $\mathsf{Pr} \infty \mathsf{fWiki}$ is called a strictly increasing (real) function.

Some sources give this as monotonic increasing function.
