(Edited)

In this video I go through important guidelines that should be followed when graphing or sketching curves. These guidelines may not apply for all curves but nonetheless it is important to go through these in a step by step manner until you get the hang of sketching curves.

Guideline H: Sketch the Curve

  • Draw asymptote lines (dashed lines).
  • Plot intercepts, inflections points, max, min.
  • Make curve hit the above points through increasing / decreasing direction, and concaving up or down, etc.
  • Plot out f'(x) at certain locations for increased accuracy.
