Web1 Sections 4.1 & 4.2: Using the Derivative to Analyze Functions • f ’(x) indicates if the function is: Increasing or Decreasing on certain intervals. Critical Point c is where f ’(c) = 0 (tangent line is horizontal), or f ’(c) = undefined (tangent line is vertical) • f ’’(x) indicates if the function is concave up or down on certain intervals. WebNow that we know the intervals where f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f is concave down before x=-1 x = −1 , concave up after it, and is defined at x=-1 x = −1 . So f f has an inflection point at x=-1 x = −1 . f f is concave up before and after x=0 x = 0 ipad flat chargerhttp://www.math.iupui.edu/~momran/m119/notes/sec41.pdf open my avery account
