Which data set has a variation, or mean absolute deviation, similar to the data set in the given dot plot?

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)

Yvaries directly as x. y =90 when x=6. find y when x=13

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
