CPM Homework Help : CCA2 Problem 1-108

Make a sketch of a graph showing the relationship between the number of people on your school's campus and the time of day.

Hint:

Before and after school hours, how many people are at school compared to the school hours?

Answer:

First quadrant graph, x axis labeled, time, y axis labeled, # of people, line starts at origin, Rises gently for a short amount of time, then is almost vertical to the top of graph, then horizontal over half of the time, then drops almost vertically, almost to the x axis, then falls slowly. Same labeled axes and graphed lines, except the horizontal line, divided into thirds, going horizontal, then drops almost vertically, 1 third of way down, then horizontal, and then up vertically, to the top horizontal line. Each new section is about a third of the first graph's horizontal line.
