DESCRIPTION

APPLICATION OF DERIVATIVE PART 2

TRANSCRIPT

  • Concavity

  • Point of Inflection

  • Curve SketchingExample: Sketch the graph ofSolution: Critical points, (f(x)=0): x=-1, x=1

  • f(-1)=0 is local minimum, absolute minf(1)=2 is local max, abs max

  • Horizontal asymptote: y=1

  • Applied OptimizationRead the problemDraw a pictureIntroduce variablesWrite equation for the unknown quantityTest the critical points and endpoints in the domain of the unknown
