domain of f(x) :
any real number, x ≠ 3
lim (x3)/(x^2  9) , x >3
= lim (x3)((x3)(x+3))
= lim 1/(x+3) , as x >3
= 1/6posted by Reiny

x = 3 is also excluded from the domain, eh? since x^29 = 0

How do we evaluate limit of, lim x> 0 [ln(x+1)/( (2^x)  1)] I tried using the substitution x+1 = e^k , when x tends to 0 so does k, which gave out, lim k>0 [ k/((2^((e^k)  1)) 1 ) ] which I simplified into( for the ease
