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 ...

What is an Inflection Point? How to Find Inflection Points

WebTo find a point of inflection, you need to work out where the function changes concavity. That is, where it changes from concave up to concave down or from concave down to … WebGiven the manner in which the question was phrased, I understood that the point of inflection of f (t) was required i.e f '' (t) = 0: solve for t. I calculated accordingly. When I received my test back, I found that my answer was marked wrong, and that the turning point or local minimum of "h" was required instead i.e f ' (t)=0 and f '' (t) > 0. WebFind the inflection points and intervals of concavity up and down of f ( x) = 3 x 2 − 9 x + 6 First, the second derivative is just f ″ ( x) = 6. Solution: Since this is never zero, there are not points of inflection. And the value of f ″ is always 6, so is always > 0 , so the curve is entirely concave upward. Example 2 csmb society
