If `f(x)=(sin([x]pi))/(x^2+x+1)`, where `[dot]`denotes the greatest integer function, then`fi son eon e``fi snoton e-on ea n dnon-con s t a n t``fi sacon s t a n tfu n c t ion``non eoft h e s e`A. `f` is one-oneB. `f` is not one-one and non-constantC. `f` is a constant functionD. None of these |

Answer» Correct Answer - C `f(x)=(sin[x]pi)/(x^(2)+x+1)` Let `[x]=n ~= "integer" ` ` :. sin[x] pi=0` or `f(x)=0` Hence, `f(x)` is constant function. |
