Show that π‘ˆ(βˆ’π‘“, 𝑝) = βˆ’πΏ(𝑓, 𝑝) and 𝐿(βˆ’π‘“, 𝑝) = βˆ’π‘ˆ(𝑓, 𝑝)


Let 𝑓 be differentiable. Show that if lim(π‘₯β†’βˆž) 𝑓(π‘₯) = 𝐿 ∈ ℝ then lim(π‘₯β†’βˆž) 𝑓 β€² (π‘₯) = 0. Provided that the latter limit is existing. Give an example where the converse is not true. Also give an example for which the limit of 𝑓 β€² is not existing even though the limit of 𝑓 is the same as given
