However, the solution $g$ lies about $e^x - 1$ for awhile before it dips below, so it's not enough to control $f$ by $g$ on a small neighborhood of 0. In fact, the length of the interval on which $g$ lies above $e^x - 1$ seems to go to infinity as $\alpha$ goes to 2, so we would need to control the length of the interval on which $f$ is dominated by $g$. | |
