i cant answer it but i can give u this Here's an example: Find the critical numbers of f (x) = 3x5 – 20x3, as shown in the figure. Here's what you do: Find the first derivative of f using the power rule. Set the derivative equal to zero and solve for x.
The critical numbers of the function would be the following:
x = pi/4 + 2npi
x = 7pi/4 + 2npi
x = 3pi/4 + 2npi
x = 5pi/4 + 2npi
I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.
