  1. Relative Extrema and More Analysis of Functions Section 5.2

  2. Critical Points vs. Stationary Points • Critical Point – A point in the domain of f where f where f has a horizontal tangent line or is not differentiable • Stationary Point – A point on the graph where the

  3. 1st Derivative Test • If extending left from and extending right from , then f has a relative maximum at • If extending left from and extending right from , then f has a relative maximum at • If has the same sign as it extend in either direction, then f does not have a relative extrema at

  4. In other words….. • If a function increases from the left and decreases to the right of , then there is a relative maximum at the point • If a function decreases from the left and increases to the right of , then there is a relative minimum at the point • If the sign of the derivative does not change, then the function either increases or decreases and does not have a relative max or min
