3.1 Extrema on an Interval

Questions that will be answered in Chapter 3: Does f have a maximum or a minimum value? Where is the function increasing or decreasing? Applications? Derivative will help us!

3.1 Extrema on an Interval

3.1 Extrema on an Interval Does this make sense? Visualize a picture in your head

3.1 Relative Extrema and Critical Number. Notice the endpoints or breaks in the graph cannot be relative extrema since it requires open intervals Only hills and valleys

Example 1: The Value of the Derivative at Relative Extrema

3.1 Critical Number Be careful don’t get confused with the converse

3.1 Finding Extrema on a Closed Interval Step 1 and 2 will find the highest and lowest relative extreme Step 3 will see if the other extremas are higher than these

Example 2: Finding Extrema on a Closed Interval
