Determining Intervals of Concavity and Inflection Points

WebMar 26, 2016 · Find the intervals of concavity and the inflection points of g ( x) = x4 – 12 x2. Answers and explanations For f ( x) = –2 x3 + 6 x2 – 10 x + 5, f is concave up from negative infinity to the inflection point at (1, –1), then concave down from there to infinity. To solve this problem, start by finding the second derivative. WebExample 1. Find 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. lake norman pulmonology and sleep

WebRemember that concavity relates directly to the sign (positive or negative) of the second derivative. In your example, notice what happens when we nudge the x-value through x=3 or through x=5. If x is slightly less than 3, then (x-3) is negative, and so is (x-3)³.
