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 . WebAnyway here is how to find concavity without calculus. Step 1: Given f (x), find f (a), f (b), f (c), for x= a, b and c, where a < c < b Where a and b are the points of interest. C is just any convenient point in between them. Step 2: Find the equation of the line that connects the points found for a and b.
