#2c you guys get 2?

#4(a) - t = 3 because thats the time when the particle stops and reverses direction; the area under the curve is greatest here

#4(b) - 1 value of t; the total area under the curve equals -8 only once, and that is when t = 3; the object goes to x = -8 when t = 3, goes to x = -5 when t = 5, and gets to x = -7 when t = 6

#4(c) - speed is decreasing because the velocity is approaching zero

#4(d) - [0,1) and (4,6] - the velocity of the particle begins to slope downwards, implying negative acceleration

#4 was the ONLY ONE THAT I DID GOOD ON LMFAO i sucked at everything else
and for the very last one, 5(c), i used the Stand and Deliver tic tac toe method, not the uv-vdu method. Do the readers not award points if I do this?
