Graph Behavior and Intervals

The video tutorial covers the concepts of increasing, decreasing, and constant intervals in graphs. It provides examples of how to identify these intervals in various contexts, such as temperature changes, voltage monitoring, roller coaster rides, car speeds, and exercise bike performance. The tutorial also includes exercises to match graphs with interval descriptions, helping students understand the practical application of these concepts.

What is an interval called when a graph moves upwards from left to right?

• Increasing

• Fluctuating

• Constant

• Decreasing

What do we call an interval where the graph remains flat?

• Increasing

• Decreasing

• Constant

• Variable

If a graph moves downwards from left to right, what is this interval called?

• Decreasing

• Fluctuating

• Increasing

• Constant

In the context of graphs, what does a constant interval indicate?

• The graph is increasing

• The graph is fluctuating

• The graph is decreasing

• The graph is staying the same
