Answer:
Option B is correct.
Step-by-step explanation:
Since, the given graph is of greatest integer function
And it is clear from the property of greatest integer function that range or value of y will always be an integer
given points in the graph are
(1,2),(4,5),(-2,-1) and (-5,-4)
Domain is the values x will take
And Range is the values of y
So, whatever value x will take due to greatest integer function it will convert to an integer
Example:
[0.5]=0
Domain will be all real numbers and range{...-4,-1,2,5....}
Hence, Option B is correct
