Determine the intervals when a function is increasing decreasing or constant

The video tutorial explains how to determine when a function is increasing, decreasing, or constant by analyzing its graph. It covers the importance of understanding the direction of the graph's output values and provides examples of how to identify these behaviors over specific intervals. The tutorial also includes practice problems for viewers to apply their understanding and concludes with a review of the key concepts.

What is the primary focus when determining if a function is increasing or decreasing?

• The thickness of the graph line

• The color of the graph

• The direction of the graph's output values

• The position of the graph on the coordinate plane

When analyzing a graph, what does it mean if the output values are getting larger?

• The graph is increasing

• The graph is constant

• The graph is oscillating

• The graph is decreasing

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

• The graph is curving

• The graph is moving upwards

• The graph is moving downwards

• The graph's output values remain unchanged

What is the significance of the interval from negative infinity to zero in the second graph analysis?

• The graph is constant

• The graph is decreasing

• The graph is undefined

• The graph is increasing

During the second graph analysis, what is observed from zero to four?

• The graph is oscillating

• The graph is constant

• The graph is decreasing

• The graph is increasing

What is the outcome when the graph's output values do not change over an interval?

• The graph is undefined

• The graph is increasing

• The graph is decreasing

• The graph is constant

In the practice problems, what is the graph's behavior from negative infinity to zero?

• The graph is decreasing

• The graph is constant

• The graph is increasing

• The graph is undefined

What is the behavior of the graph from two to infinity in the practice problems?

• The graph is undefined
