Increasing/decreasing and the First Derivative test Section 3-3 Increasing/decreasing and the First Derivative test
Graphs that are going up or increasing have slopes that are? POSITIVE Graphs that are going down or decreasing have slopes that are? NEGATIVE
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
Consider: max decreasing increasing increasing min
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
1.) Determine the intervals where the function is increasing and decreasing Interval x Result
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
3.) Determine where the function is increasing and decreasing and find All extrema Interval x Result
4.) Graph, then determine where the function is increasing and decreasing
5.) Classify the relative extrema of and find the intervals where increasing and decreasing Interval x Result
6.) Classify the relative extrema of and find the intervals where increasing and decreasing Interval x Result
