You’ll learn

  • Find points of inflection by solving f''(x) = 0
  • Sub the x-value into the original f(x) to state the inflection point as (x, y)
  • Distinguish f'(x) = 0 (turning points) from f''(x) = 0 (inflection)
  • Prove a function has no points of inflection via the numerator-non-zero argument
