Determine concavity of the function 3x5-5x3
WebInflection points are found in a way similar to how we find extremum points. However, instead of looking for points where the derivative changes its sign, we are looking for points where the second derivative changes its sign. Let's find, for example, the inflection points of f (x)=\dfrac {1} {2}x^4+x^3-6x^2 f (x) = 21x4 +x3 −6x2. WebOct 12, 2016 · Explanation: Points of inflection are points on the graph at which the concavity (and the sign of the second derivative) change. y = 3x5 −5x3. y' = 15x4 …
