Answer:
Option b is right answer.
Step-by-step explanation:
Given is a step function of graph with discontinuities at all integers.
We find that f(0.1) = 2, f(1.1) = 3...
i.e. we have thus found that this is greatest integer function shifted 2 units up vertically.
f(x) = greatest integer function x +1
Hence option is option b
