lim x-> 0+ f(x)= ∞
lim x-> 0- f(x)=0
we have f'(x)= e1/x - e1/x/x
= e1/x(1-1/x)
so f(x) is increasing in (1,∞)
decreasing in (0,1)
for x belongs ro R-
we have limx->-∞ f(x) =-∞
the graph is -∞ at -∞, increases to 0 at 0, is discontinuous at 0, decreases to obtain a minima at x=1, or f(x)=e, and then increases to infinity as x→∞
inshort its gonna be the same as above.. :):):)
cheers!!
