6 Rev.S08 Is the Function Increasing or Decreasing? The concept of increasing and decreasing relate to whether the graph of a function rises or falls . Moving from left to right along a graph of an increasing function would be uphill . Moving from left to right along a graph of a decreasing function would be downhill . We speak of a function f increasing or decreasing over an interval of its domain . http://faculty.valenciacc.edu/ashaw/ Click link to download other modules.

8 Rev.S08 Example Use the graph of shown below and interval notation to identify where f is increasing or decreasing . http://faculty.valenciacc.edu/ashaw/ Click link to download other modules. Solution Solution Moving from left to right on the graph of f , the y-values decreases until x = 0, increases until x = 2, and decreases thereafter. Thus, in interval notation f is decreasing on
