Webat x = −1 the function is decreasing, it continues to decrease until about 1.2 it then increases from there, past x = 2 Without exact analysis we cannot pinpoint where the curve turns from decreasing to increasing, so let us just say: Within the interval [−1,2]: the curve decreases in the interval [−1, approx 1.2]
WebSo $xe^{-x}$ achieves its maximum in $[0, \infty)$ at $x=1$, which is $1/e$. However, to prove that it's bounded by $1/e$, I need to prove that as $x$ goes to infinity, $xe^{-x}$ … Webf(x)=sinx−ax is decreasing in R if Easy View solution > Let f be a function defined on [a, b] such that f(x)>0, for all xe (a, b). Then prove that f is an increasing function on (a, b). …
