Ineed the answer to this asap. you just need to match each thing on the left to its correct answer on the right.
match the following items.

complete the proof for theorem 3-13. (if you dont know what this theorem is i added a picture that explains it so you can )

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 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)
