AP Calculus AB

1. AP Calculus AB Day 1 Section 3.1 Perkins

2. Extreme Value Theorem (EVT) If f is continuous for all x in [a,b] then f must have both an absolute maximum and an absolute minimum value in the interval [a,b]. Examples: Absolute Maximum Abs Max Abs Max Abs Min Abs Min Absolute Minimum

3. Extrema – highest and lowest function values when the derivative is either zero or undefined Horizontal tangents Vertical tangents 3 types Absolute (See previous slide) Relative -- occur only at critical numbers (cannot be at endpoints of an interval) ‘Local’ -- compared to the points we can see (can be at endpoints and critical numbers) A/R/L A/L A/L Local R/L Local A/L Local R/L A/R/L A/R/L Extrema will only occur at endpoints or critical numbers!

4. Extrema occur at either endpoints or critical numbers. f(x) is continuous on [-1,3]. Minimum Find the extrema of on [-1,3]. Maximum Vertical tangents Horizontal tangents
