Hello. I hope this is the right place to post this: why is ⎮x⎮÷ (1+x^2) bounded at 1/2 , meaning ≤ 1/2? thanks a lot

notice that: you can also easily find that the function has two symmetrical maxima points at 1 and -1 f(1) = f(-1) = 0.5 from the combination of these two facts we conclude that:
but then where is the 1/2 coming from?
Have you read my post carefully (f(1) = f(-1) = 0.5) ?
oh sorry. i did not see the second part when i posted it, it did not appear. it just appeared the part on the limit. i don't know how. with the second part added is much better. now i got it thanks!
