Increasing/decreasing and the First Derivative test
Section 3-3 Increasing/decreasing and the First Derivative test
2
Graphs that are going up or increasing have slopes that are?
POSITIVE Graphs that are going down or decreasing have slopes that are? NEGATIVE
3
Increasing and Decreasing
Let f be a differentiable function in the interval (a,b) then If for x in (a,b), then f is decreasing If for x in (a,b), then f is increasing If for x in (a,b), then f is constant and has a horizontal tangent
4
Consider: max decreasing increasing increasing min
5
The First Derivative Test
Let f be a differentiable function with If changes from positive to negative, then f has a relative maximum at c If changes from negative to positive, then f has a relative minimum at c
6
1.) Determine the intervals where the function
is increasing and decreasing Interval x Result
7
2.) Determine the intervals where the function
is increasing and decreasing Interval x Result Def: Strictly Monotonic: A function that is either increasing or decreasing on the entire interval is said to be strictly monotonic
8
3.) Determine where the function is increasing and decreasing and find
All extrema Interval x Result
9
4.) Graph, then determine where the function is increasing and decreasing
10
5.) Classify the relative extrema of
and find the intervals where increasing and decreasing Interval x Result
11
6.) Classify the relative extrema of
and find the intervals where increasing and decreasing Interval x Result
