  1. 3.6 – Critical Points & Extrema

  2. Vocabulary • Critical Points – points on a graph in which a line drawn tangent to the curve is horizontal or vertical • Maximum • Minimum • Point of Inflection

  3. Maximum • When the graph of a function is increasing to the left of x = c and decreasing to the right of x = c.

  4. Minimum • When the graph of a function is decreasing to the left of x = c and increasing to the right of x = c

  5. Relative Extrema • A maximum/minimum of a function in a specific interval. • It is not necessarily the max/min for the entire function

  6. Absolute Extrema • Extrema – the general term of a maximum or minimum. • Absolute Extrema – the greatest/smallest value of a function over its whole domain

  7. Point of Inflection • Not a maximum or minimum • “Leveling-off Point” • When a tangent line is drawn here, it is vertical

  8. Testing for Critical Pointslet x = a be the critical point for f(x)h is a small value greater than zero Pictures will be drawn on the board

  9. Let’s Look at Page 176 # 4 – 5, 8 – 11 We will do these together as examples
