Webthe function has the blue graph. the first derivative is zero when the function reaches an extremum, its graph is the red one. the second derivative gives information on curvature. It is positive when the function decreases and increases just after. it is negative when the function increases and then decreases. its graph is the green one. WebFirst Derivative Test Steps. Below are the steps involved in finding the local maxima and local minima of a given function f (x) using the first derivative test. Step 1: Evaluate the first derivative of f (x), i.e. f’ (x) Step 2: Identify the critical points, i.e.value (s) of c by assuming f’ (x) = 0. Step 3: Analyze the intervals where the ...
WebNov 10, 2024 · The first derivative is f ′ (x) = 3x2 − 12x + 9, so the second derivative is f ″ (x) = 6x − 12. If the function changes concavity, it occurs either when f ″ (x) = 0 or f ″ (x) is undefined. Since f ″ is defined for all real numbers x, we need only find where f ″ (x) = 0.
