Exercise 11.1. Use the strategies of this section to sketch the graphs of each of the following functions 1. f(x) = x-1 Vx 2+1 2. g(x) = ex2 3. f(x) = Vxe-2" (Given lim f(x) = 0, which is a limit we can't yet compute algebraically 20-+0o but we'll prove later using l'Hopital's rule) 4. f(x) = xe3 ( where lim xe3x = 0) - -00 5. g(x) = xln(x) ( where lim xln(x) = 0) x-0+
