Answer:
C
Step-by-step explanation:
The graph is of the "greatest integer" (floor) function shifted up by 3 units. Hence the appropriate choice is C.
[tex]y=\lfloor x\rfloor+3[/tex]
__
The greatest integer less than or equal to x for 0 ≤ x < 1 is 0, so the horizontal line segment at f(x)=3 indicates 3 has been added to the function.
_____
Additional comment
The brackets used for floor and ceiling functions only have horizontal bits below or above (respectively) the enclosed argument. The usual square brackets [ ] need explanation as to their meaning if they are intended to indicate one or the other of these functions.
