Let `f=[(x,(x^(2))/(1+x^(2))):x in R]` be a function from R into R.Determine the range

f={(x,(x^(2))/(1+x^(2))):x in R} be a function from R into R. Determine the rage of f .

If f(x)=(x^(2)-2x+4)/(x^(2)+2x+4)x in R then range of function is

If f(x)=(x^(2)-2x+4)/(x^(2)+2x+4),x in R then range of function is

f ={(x,x^2/(x^2+1)): x in R} ,be a function R into R,range of 'f' 1)[0,1) 2) (-oo,oo) 3) (0,oo) 4) R^+

Let f(x)=(1)/(1+|x|) ; x in R the range of f is

Let f:R rarr R and f(x)=(3x^(2)+mx+n)/(x^(2)+1) . If the range of this function is [-4,3], then the value of (m^(2)+n^(2))/(4) is ….

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