can exist an smooth function with the property(adsbygoogle = window.adsbygoogle || []).push({});

[tex] y(\infty) =0 [/tex] and [tex] y'(\infty) =1 [/tex] ?

the inverse case, a function that tends to 1 for big x and whose derivative tends to 0 is quite obvious but this case i am not sure if there will exist
