Application of Differentiation

  • The Extreme Value Theorem

If f is continuous on a closed interval [a,b], f has an absolute max value f(c)and absolute min value f(d) at c and d in the interval [a,b]

  • Fermat's Theorem

If f has a local max or min at c, and f'(c) exists, f'(c)=0

  • Critical Number

A number c in the domain of f such that f'(c)=0 or f'(c) doesn't exist

  • Closed Interval Method


y=x2 Minimum value:0; No Maximum Value

y=x3 No minimum value; No maximum value
