f(x)=1/sqrt(x^(12)-x^(9)+x^(4)-x+1) . Then domain of function f(x) is

The domain of the function f(x)=(sqrt(x^(12)-x^(3)+x^(4)-x+1))/(2sqrt(2{x}^(2)-3{x}+1)) (where {} denotes the fractional part functio) is

The domain of definiton of the function f(x)=(1)/(sqrt(x^(12)-x^(9)+x^(4)-x+1)) , is

The domain of definiton of the function f(x)=(1)/(sqrt(x^(12)-x^(9)+x^(4)-x+1)) , is

The domain of definiton of the function f(x)=(1)/(sqrt(x^(12)-x^(9)+x^(4)-x+1)) , is
