value of function
f(x)= [x] + (x-[x])^2.
where [x] means largest integer not exceeding x.
then find set of all values taken by f

Re: value of function
I think the set will be infinite. does anyone has anything else in mind?

Re: value of function
yes for n=2, [n]=2 but when n=1.6, [n]=1
. the set should be infininte#7 2012-11-21 05:21:57

That is true. You can even plot it to see that the range is R (ie. the reals).
The limit operator is just an excuse for doing something you know you can't.
