The total number of words, Wt). that a person can memorize in t'minutes is shown in the graph below. Complete parts a) and b) to the right. M (24.25) (16.20) . \\ (36.25) 16 24 323640 Note: Graph not drawn to scale. a) Find the average rate of change of M as t changes from 0 to 8: from 8 to 16; from 16 to 24; from 24 to 32; from 32 to 36. The average rate of change of M as t changes from 0 to 8 is D words/min. (Simplify your answer.) The average rate of change of M as t changes from 8 to 16 is D wordslmin. (Simplify your answer.) Tile average rate of change of M as t changes from 16 to 24 is D words/min. (Simplify your answer.) The average rate of change of M as t changes from 24 to 32 is D words/min. (Simplify your answer.) The average rate of change of M as t changes from 32 to 36 is [:1 wordsimin. (Simplify your answer.) b) Explain the behavior of the average rates of change after 24 min. 0 A. The graph becomes vertical and therefore has no slope. Q B. The graph becomes vertical and therefore has an undened alone
