The function `f(x)=(x)/(x^(2)+1)` from R to R is

If f:R rarr R, then the range of the function f(x)=(x^(2))/(x^(2)+1) is

The range of the function f(x)=(x)/(1+x^2),x in R , is

The function f:R rarr R, f(x)=x^(2) is

The function f:R rarr R, f(x)=x^(2) is

If f:R rarr R is a function f(x)=x^(2)+2 and g:R rarr R is a function defined as g(x)=(x)/(x-1), then (i) fog (ii) go f

If f,g,\ h are three functions defined from R\ to\ R as follows: the range of h(x)=x2+1

Let f:R->R be a function defined by f(x)=x^2-(x^2)/(1+x^2) . Then:

Range of the function f: R rarr R, f(x)= x^(2) is………

If f: R to R is defined by f(x)=x-[x]-(1)/(2) for all x in R , where [x] denotes the greatest integer function, then {x in R: f(x)=(1)/(2)} is equal to

If f: R to R is defined by f(x)=x-[x]-(1)/(2) for all x in R , where [x] denotes the greatest integer function, then {x in R: f(x)=(1)/(2)} is equal to
