A) \[f(x)>f(y)>f(z)\]
B) \[f(x)<f(y)<f(z)\]
C) \[f(y)<f(x)<f(z)\]
D) \[f(y)<f(z)<f(x)\]
Correct Answer: C
Solution :
[c] Let \[f(x)\ne 2\] be true and \[f(y)=2,f(z)\ne 1\] are False \[\Rightarrow f(x)\ne 2,f(y)\ne 2,f(z)=1\] \[\Rightarrow f(x)=3,f(y)=3,f(z)=1\] but then function is many one, similarly to other cases.You need to login to perform this action.
