Let `f : R to and f (x) = (x (x^(4) + 1) (x+1) +x ^(4)+2)/(x^(2) +x+1),` then `f (x)` is :

Let f(x)={x^(2) if 1 4

If f: R to R is defined by f(x)=(x^(2)-4)/(x^(2)+1) , then f(x) is

Let f:R to R be defined as f (x) =( 9x ^(2) -x +4)/( x ^(2) _ x+4). Then the range of the function f (x) is

Let f:R to R be defined as f (x) =( 9x ^(2) -x +4)/( x ^(2) _ x+4). Then the range of the function f (x) is

Let f : R rarr R be defined by f (x) = x^2 - 3x + 4 for all x in R , then f^-1 (2) is equal to

Let f(x) = x - [x] , x in R then f(1/2) is

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

If f (x)=4x -x ^(2), then f (a+1) -f (a-1) =

Let f(x) = {(x^(4)-5x^(2)+4)/(|(x-1)(x-2)|) x ne 1,2),(6, x=1), (12, x =2):} . Then, f(x) is continuous on the set

Let f (x) = |x – 2| + |x – 3| + |x – 4| and g(x) = f (x + 1) . Then
