The only critical point is at x = 0. Let's try using the second derivative to test the concavity to see if it is a local maximum or a local minimum. Since the second derivative is zero, the function is neither concave up nor concave down at x = 0. ... Let's test to see if it is an inflection point.read more >>+119962023-06-23 09:57:04
