Here's the Solution to this Question
Let f be a function from Z to R, such that f(x)=x/10
Graph of f(x) in its domain:
Now, Interval in which f(x) to be determined is ( )
So, a= and b=
and f(a)= and f(b)=
Hence f(a)< f(b)
So, it is clear that f(a)<f(b) and f'(x)>0
Hence f(x) is Strictly Increasing function.
