Critical numbers of a function. The first derivative test for local extrema.
  • What is a critical number?
  • What is the first derivative test?
  • What is a local extreme value?
  • How do you find local minimum and local maximum values of a function?
  • How do you pick test points for critical points?
Discussed in this video are critical numbers, critical points, and how to determine whether a point of a function is a local minimum, local maximum, or neither using the first derivative test. Several examples are done, and the common, accepted method for making a sketch of f’(x) for critical points is shown, as well as picking test points and determining local minimum and local maximum points for the function. This is a truly useful video for any Calculus student.
