If triangle PQR is plotted, it will have the following coordinates, P(-4, 0), Q(4, 2) and R(-2, 4 If point R is translated 4 units right and 7 units down, what are the coordinates of R’? Explain your answer
[ it is a coordinate graph with a 12 y axis and a 8 x axis I couldn’t put in a picture it’s too big ]

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)
