WebDec 18, 2024 · The inflection point occurs at x = p3. You can show it by using the symbolic 'diff' to find the second derivative of f with respect to x and finding the x that makes it zero. That occurs when 10^ ( (p3-x)*p4)) is equal to 1 which forces x to equal p3. on 18 Dec 2024 Theme Copy double (solve (f,'MaxDegree',3)) Thanks, Iddo Lalitesh on 30 Jan 2024 WebDec 20, 2024 · 5.4: Concavity and Inflection Points. We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f ′ ( x) > 0, f ( x) is increasing. The sign of the second derivative f ″ ( x) tells us whether f ′ is increasing or decreasing; we have seen that if f ′ is zero and increasing at a ...

WebGiven f (x) = x 3, find the inflection point (s). (Might as well find any local maximum and local minimums as well.) Start with getting the first derivative: f ' (x) = 3x 2. Then the second derivative is: f " (x) = 6x. Now set the second derivative equal to zero and solve for "x" to find possible inflection points. 6x = 0. can i have multiple aws accounts
