Answer:
B. y = [x] + 3
Step-by-step explanation:
The answer to this graph would be
B. y = [x] + 3
This is because the graph is translated up by 3 units. Such that a value of 0 passed into x would give us a y value of 3 on the graph, which is represented as a black dot. For a value of -4 passed as x, the largest integer that is less than -4 would be -4 itself and if we add 3 to it due to following this function, we get a y value of -1 which is what is represented in the graph.
