Which of the following functions is graphed below ? (:

correct option is C.) y = [x] + 5

Step-by-step explanation:

The greatest integer function gives the largest integer less than or equal to that number.

The graph of greatest integer function Y = [x] is shown in figure-1

so, if we add 5 in function Y = [x] then this is shown as given in figure.

hence correct equation of graph is Y = [x]+5
