WebAug 4, 2014 · 1 Answer. We need to find where the concavity changes. These are the inflection points; usually it's where the second derivative is zero. Our function is y = f (x) = xex. Set f'' (x) = 0 and solve to get x = -2. The second derivative changes sign at -2, and so the concavity changes at x = -2 from concave down to the left of -2 to concave up to ...
