f(0)- = 0 ? [11][11]

it seems correct to me,aur maine rough diagram banaya hai, to the scale nahi :)

just check first & second derivative

haan bhai just check the limits

f(0-)=lim(h→0+)-he(-1/h)=0

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!!
