Question

Which of the following functions is graphed below?

A. y = [x] - 6
B. y = [X] +6
C. y = [x] + 4
D. y = [x] - 4

Answer 1

Answer: A

Step-by-step explanation:

Take the point (0, -6). The floor of 0 is 0, so normally it would be (0, 0). However, since the y coordinate is -6, not 0, we know it was translated down 6 units. Therefore, the answer is A.
