Text Solution
Verified by ExpertsThe correct answer is:
B
f(x) = e x & g(x) = λ nx
are image of each other in line mirror y = x hence minimum distance between these will be equal to distance between parallel tangents of f(x) & g(x) which are parallel y = x.
⇒ e x = 1 & = 1 
⇒ x = 0 & x = 1
P ≡ (0, 1) ; Q = (1 , 0)
PQ =
