If f : R → R is an invertible function such that f(x) and f –1 (x) are also mirror image to each other about the line y = –x, then
Text Solution
Verified by ExpertsThe correct answer is:
A
Since f(x) and f –1 (x) are symmetric about the line y = –x.
If ( α, β ) lies on y = f(x) then (– β , – α ) on y = f –1 (x) ⇒ (– β , – α ) lies on y = f(x) ⇒ y = f(x) is odd.
