If f : R→R and F(x) =sin(π{x})X4+3x2+7, Where { } is a fractional part of x , then

f is not one -one and non -constant

If f : R→R and F(x) =sin(π{x})X4+3×2+7, Where { } is a fractional part of x , then

If f : R→R and F(x) = $\frac{\sin (π {x})}{X^{4} + 3 x^{2} + 7}$ , Where { } is a fractional part of x , then

f (x) = $\frac{\sin (π {x})}{X^{4} + 3 x^{2} + 7}$
Here , f (1 /2 )= f(-1 /2)
Clearly, f(x) is not one -one and also it is dependent on x.
