How would i find certain values for the function cos(x)/x?

Question

Really the domain and range for this function, whether it is even or odd and what the graph looks like. Also what is the limit as the function approaches infinity.

Answer 1

Domain i al x except 0
Range is - infinity to plus infinity
It is an odd function because -f(x) = f(-x)
As x--> +/- infinity, f(x) --> 0
