WebSolution: f ′ ( x) = 3 x 2 − 6 x = 3 x ( x − 2) Since f ′ is always defined, the critical numbers occur only when f ′ = 0, i.e., at c = 0 and c = 2. Our intervals are ( − ∞, 0), ( 0, 2), and ( 2, ∞). On the interval ( − ∞, 0), pick b = − 1 . (You could just as well pick b = − 10 or b = − 0.37453, or whatever, but − 1 ...

Web1 Sections 4.1 &amp; 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. WebIf a function changes from concave upward to concave downward or vice versa around a point, it is called a point of inflection of the function. In determining intervals where a function is concave upward or concave downward, you first find domain values where f″ (x) = 0 or f″ (x) does not exist.
