lim(x→0) (1 + e^-1/x)/(1 - e^-1/x) is equal to
lim(x→0) (1 + e-1/x)/(1 - e-1/x) is equal to(A) 1 (B)-1 (C) 0 (D) Does not exist
The limit does not exist because the expressions on the numerator and denominator are both approaching infinity. When x approaches 0, the numerator approaches infinity and the denominator approaches -infinity. As a result, the fraction is undefined.
