A) \[{{x}^{2}}\]
B) \[1-{{x}^{2}}\]
C) \[1+{{x}^{2}}\]
D) \[{{x}^{2}}+x+1\]
Correct Answer: C
Solution :
[c] \[{{x}^{2}}F(x)+F(1-x)=2x-{{x}^{4}}\] ...(1) Replacing \[x\]by \[1-x,\]we get \[{{(1-x)}^{2}}F(1-x)+F(x)=2(1-x)-{{(1-x)}^{4}}\] ...(2) Eliminating \[F(1-x)\] from (1) and (2), we get \[F(x)=1-{{x}^{2}}.\]You need to login to perform this action.
