The Mironenko reflecting function is like a magic mirror that can turn numbers into other numbers. For example, if you put in the number 2, the reflecting function can turn it into a whole bunch of other numbers like 1.5, 1.25, 1.125, and so on.
This magic mirror is actually really helpful for mathematicians who study something called probability theory. They use it to help them figure out how likely it is for certain things to happen, like how often a coin will land on heads or tails when you flip it.
So basically, the Mironenko reflecting function is a cool tool that helps smart people do really complicated math stuff!
