These intervals are … WebConsider the following. (If an answer does not exist, enter DNE.) f(x) = ln(x2 + 7) Find the interval(s) on which f is concave up. (Enter your answer using interval notation.) Find …
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
