Solve the problem.Your friend, who wanted to improve her physical fitness for an event to take place on July 1st, started a diet and exercise regimen on January 1st. She measured her weight on that day and on the 1st of each month thereafter until July 1st. Having met her goals on July 1st, she decided to continue with the regimen and record keeping for the remainder of the year. The data is used to construct a graph, where the number of months since July 1st is the input variable, and the weight lost or gained during each month is the output variable. Note that July 1st is taken to be time zero, since this date is of interest as a reference point. If the graph tells you that there was no weight change for February, where is the point for February located?
