We start by restating the scenario: f is continuous on R and strictly decreasing, and F is an antiderivative of f (so F' = f). We are to evaluate which statements must be true. Option 1: F has at least one critical point. - A critical point of F occurs where F' = f = 0 (or where F' is undefined). Since f is strictly decreasing and continuous, it is not guaranteed to cros......Login to view full explanation
