The function `f : R rightarrow R` is given by `f(x) = x^3-1` is

Check whether the function f: R rarr R given by f(x) = x^2 , is 1 - 1 and onto or not.

If f = R rightarrow R is defined by f(x) = |x| , then,

Show that the function f:R rarr R given by f(x)=x^(3)+x is a bijection.

The function f:R rarr R is defined by f(x)=3^(-x)

If the function f:R to R is given by f(x)=(x+3)/(3) and g:R to R is given g(x)=2x-3 , then find (i) fog (ii) gof. Is f^(-1)=g ?

The function f:R to R given by f(x)=x^(2)+x is

The function f:R to R given by f(x)=x^(2)+x is

Show that the function f:R-{3}rarr R-{1} given by f(x)=(x-2)/(x-3) is a bijection.

Show that the function f: R->R given by f(x)=x^3+x is a bijection.
