WebStep 3: Analyzing concavity Step 4: Finding inflection points Now that we know the intervals where f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f is concave down before x=-1 x = −1 , concave up after it, and is defined at x=-1 x = −1 . So f f has an inflection point at x=-1 x = −1 . WebMar 26, 2016 · 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.
