Proof. Proceed by contradiction. Suppose that f has more than one root in (0,∞). Let r1 and r2, with r1 < r2, be two consecutive such roots (note that we can always find two consecutive roots r1 and r2 because f (r) > 0 for any root r). From the hypothesis, we have f (r1) > 0 and f (r2) > 0. Since f ′ is continuous at r1, there exists an 0 < 2 < (r2− r1) such that f (x) > 0 in the interval (r1,...
