The table below shows the value of a function. Which best describes the function, based on the average rates of change?
The function is linear because the average rates of change are all the same, 4.

B.
The function is linear because the average rates of change are all the same, 2.

C.
The function is not linear because each average rate of change is 4 times the previous rate of change.

D.
The function is not linear because each average rate of change is 2 times the previous rate of change.

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
