If `f:R->R` `f(x)=x/(x^2+1) AA x in R` is

Show that the function f:R->R defined by f(x)=x/(x^2+1) AA x in R is neither one-one nor onto. Also if g:R->R is defined by g(x)=2x-1 find fog(x)

Show that the function f : R rarr R defined by : f(x) = x/(x^2+1) AA x in R , is neither one-one nor onto.

Show that the function f:R rarr R defined by f(x)=(x)/(x^(2)+1)AA x in R is neither one-one nor onto.Also if g:R rarr R is defined by g(x)=2x-1 find fog(x)

f:R rarr R defined by f(x)=(x)/(x^(2)+1),AA x in R is

Let f : R-{1} to R be defined by f(x) =(1+x)/(1-x) AA x in R -{1} then for x ne +-1, (1+f(x)^(2))/(f(x)f(x^(2))) =………….

The function f: R to R defined by f(x) =x-[x], AA x in R is

If f:R to R be the function defined by f(x) = sin(3x+2) AA x in R. Then, f is invertible.

If f:R to R be the function defined by f(x) = sin(3x+2) AA x in R. Then, f is invertible.
