We can even sketch a few examples for which 𝑓 is positive on two … WebAlso tried to show that f(x) has no turning points over the interval, but I can't seem to get anywhere. The latest idea was to try to find a function such that $ f(x) \geq g(x) \geq 0 $ over (0,1) but this just means I have to deal with 2 functions rather than 1. Has anyone got any ideas how I might proceed? Thanks, John. how to ride in the maw
