Answer:
The correct answer is D. 3.
Step-by-step explanation:
Let's review the change of the linear function, according to the table:
When x = - 2, f(x) = -13
When x = - 1, f(x) = -10 (Change + 3)
When x = 0, f(x) = -7 (Change + 3)
When x = 1, f(x) = -4 (Change + 3)
When x = 2, f(x) = -1 (Change + 3)
Therefore, the change of the linear function is constantly +3.
The correct answer is D. 3.
