The graph above is the derivative f ‘(x) of a function y=f(x). What information about f(x) can you obtain from its derivative? Be as detail as possible.
GIVEN THE GRAPH OF f(x) CHOOSE THE GRAPH OF f ‘(x) In the next slides you will be presented (on the left) with the graph of a function, and on the right with some choices for its derivative function. Choose its derivative functionand • Give reason for your choice • For each of the graphs you did not choose give one reason why it was not chosen
GIVEN THE GRAPH OF f’(x) CHOOSE THE GRAPH OF f (x) In the next slides you will be presented (on the left) with the graph of the derivative function, and on the right some choices for the graph of the function (ananti-derivative function). Choose the graph corresponding to the function. • Give reason for your choice • For each of the graphs you did not choose give one reason why it was not chosen
GIVEN THE GRAPH OF f’(x) CONSTRUCT A GRAPH OF f (x) Click on the link below to work on this activity. The graph in red is the derivative function of a function f(x). I will do the first one with your help. You then practice on one. Finally, we will see what group is the best. Total time: 10 minutes Reconstructing a function from f ’
First Derivative and Second Derivative The derivative function of the derivative function is called the secondderivative function
Function, First, and Second Derivatives Local Max of f ’(x) Inflection Point of f(x) Change Concave up to concave down f “ changes from positive to negative
Function, First, and Second Derivatives f “ changes from negative to positive Inflection Point of f(x) Change Concave down to concave up Local min of f ’(x)
PRACTICE Select the correct answer in each case. • On an interval where a function is concave up,the first derivative is • positive -- negative • Increasing -- decreasing • any of the above is possible • On an interval where a function is concave up, the second derivative is • Positive -- negative • Increasing -- decreasing • any of the above is possible
Identifying f, f’, f’’ You will be presented with three graphs. They represent f, f ‘, f” . Determine which one is which. Give reasons for your choice
Practice For each of the functions below determine: • Domain • Where the function is increasing/decreasing • Where the function is concave up/down • Any critical points • Any inflection points
