Exercises: Describe Qualitatively the Functional Relationship Between Two Quantities by Analyzing a Graph

Work through each section in order. For these problems, you describe and sketch graphs using words like increasing, decreasing, constant, linear, and nonlinear. You do not need exact numbers — focus on direction, shape, and relative steepness.

$A curve on a Time vs Temperature graph that slopes downward from left to right but stays well above the horizontal axis.$

The graph shows the temperature of a room during one evening. Which statement best describes the whole graph?

The temperature is decreasing the whole time, but it stays positive (above the axis).

The temperature becomes negative because the graph goes down.

The temperature is increasing because the line is moving to the right.
