Find intervals that a function is increasing and decreasing

The video tutorial explains how to determine if a graph is increasing or decreasing by analyzing the X and F of X values. It emphasizes reading graphs from left to right and using X values to write intervals of increase or decrease. The tutorial highlights common mistakes, such as confusing Y values with X values, and provides examples of how to correctly identify and write these intervals.

What does it mean for a graph to be increasing or decreasing?

How do we determine if the graph is increasing or decreasing based on the X values?

What is the significance of F of X in determining the behavior of the graph?

What intervals of X values correspond to the graph decreasing?

Explain the common mistake people make when identifying increasing or decreasing intervals.
