This is the answer key I just don't know why this is labeled the way it is.The question is:For this x(t) graph, answer (and explain briefly) the following:A) "circle" any regions where speed is constantB) "square" any regions where velocity is positive.C) "triangle" any regions where the acceleration is negative.

Question 3: For this x(t) graph, answer (and explain briefly) the following A) "circle" any regions where speed is constant B) "square" any regions where velocity is positive. C) "triangle" any regions where the acceleration is negative. (20) X
