WebNow 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 . f f is concave up before and after x=0 x = 0 WebMath Calculus Let f (x) = -x4-9x³+2x+8. Find the open intervals on which is concave up (down).
