Quiz (1): What is this function?
For various reasons there have been no articles in recent weeks; now we are restarting on a regular basis!
A the first topic for this new season, here is a little quiz. I have a function:
- For 0 it yields 0.
- For 1 it yields 1.
- For 2 it yields 4.
- For 3 it yields 9.
- For 4 it yields 16.
The question: what is the value for 5?
Answer next Wednesday (at least it will be Wednesday in some time zone).

If you are asking like this, there is a certain chance that it is not 25.
5
There are an infinite number of functions such as f(0)=0 & f(1)=1 & f(2)=4 & f(3)=9 & f(4)=16 & f(5)=25.
f(x)=x² is not necessarily the most interesting, the most simple, or the one you have in mind.
I hate those IQ test questions…
