Which graph represents the step function f(x)=⌊x−1⌋ ?

The correct option is fourth.

Explanation:

The given function is a greatest integer function or a step function.

In these type of functions the value of the function is always an integer and it is a piecewise function which is defined as,

In the given function is we have (x-1) instead of x, so we will get,

It means the value of function is the integer n for all the number lies from (n+1) to (n+2), Where (n+2) is not included.

Similarly the value of function from 1 to 2, where 2 is excluded. Therefore the graph 4 represents the graph of the given function.
