Derivatives - Points of local maxima and local minima

  • Definition of a local maximum and a local minimum
  • Key points on the graph of a function
  • Determining local maxima and local minima algebraically
  • Identifying critical points
  • Using the first derivative test
    • If f’(x) changes sign from positive to negative, there is a local maximum at x.
    • If f’(x) changes sign from negative to positive, there is a local minimum at x.
  • Using the second derivative test
    • If f’’(x) > 0, there is a local minimum at x.
    • If f’’(x) < 0, there is a local maximum at x.
  • Examples and applications
    • Finding local extrema on real-world problems
