23:09:40 `qNote that there are four questions in this assignment. `q001. Recall the stock value problem, where March, July and December values were $5000, $5300 and $5500. Construct a graph of stock value vs. number of month (e.g., 1 for Jan, 2 for Feb, etc.). You will have three points on your graph, one corresponding to the March value, one to the July value, and one to the December value. Stock value will be on the y axis and month number on the x axis. Your first point, for example, will be (3, 5000), corresponding to $5000 in March. Connect your three points with straight lines--i.e., connect the first point to the second and the second to the third. What is the slope of your line between the first and second point, and what is the slope of your line between the second in the third point? Recall that slope is rise / run.
......!!!!!!!!...................................
RESPONSE --> The slope of the 1st and 2nd point is 75. The slope of the 2nd and 3rd point is 40. confidence assessment: 2

23:20:18 `q002. Look at your results for the slopes, and look the results for the average rates of change. What do you notice? In what way then does the graph represent the average rate of change?
......!!!!!!!!...................................
RESPONSE --> In the graph, there seems to be a significant growth rate between the 1st and 2nd data points. It then seems to level off at a steady growth rate from the 2nd and 3rd data points. confidence assessment: 1

23:32:34 `q003. To what extent do you think your graph, consisting of 3 points with straight line segments between them, accurately depicts the detailed behavior of the stocks over the 9-month period?
......!!!!!!!!...................................
RESPONSE --> The graph does not do a good job of depicting the behavior of the stocks. There is a considerable amount of time that is not documented on this graph, thus leaving a information 'gap' on the behavior of the stocks. confidence assessment: 2

23:34:30 `q004. From the given information, do you think you can accurately infer the detailed behavior of the stock values over the nine-month period?
......!!!!!!!!...................................
RESPONSE --> No, as much as stocks change from day to day, this only gives us a general idea on the growth rate over an extended period of time. confidence assessment: 2
