lmao did you fail english at school?

Nobody is going to do your homework for you, OP. Either you do the homework, or you're not cut out for this, because there will be things a lot worse.

To prove it's periodic, you only need to show that f (x) = f (kx +c), which he did.

it didn't answer question

no he didn't, he stated it. The proof isn't trivial.

it's literally half a line worth of paper

Please pass Algebra 1 before posting on this board

Tell me what the definition of periodic is.
The normal definition is that f (x) =(kx+c) for k,c belonging to the reals.

So to prove a function is periodic, you only need to find the set of k,c satisfying the condition.

I overestimated your intelligence. Now kys or quit your study, because you can't handle this simple example.
