Prove that the function `f: R^(+) rarr [-5, oo)` defined by `f(x)= 9x^(2) + 6x-5`, is invertible

Prove that the function f: [0,oo)rarr R , given by f(x) =9x^(2) +6x -5 is not invertible. Modify the codomain of the functions to make it invertible, and hence find f^(-1)

The function f:R rarr R defined by f(x) = 6^x + 6^(|x| is

The function f:R rarr R be defined by f(x)=2x+cosx then f

f:R->R defined by f(x) = x^2+5

Prove that the function f : R to R defined by f(x)= 2x+ 7 , is invertible. Hence find f^(-1)

Prove that the function f:R - {-1} to R -{1} , defined by f(x)=(x)/(x+1) is invertible.

if the function f: R rarr R given be f(x)=x^3 + ax^2 + 5 x + sin 2x is invertible then

Consider a function f:R rarr R defined by f(x)=x^(3)+4x+5 , then

Show f:R rarr R defined by f(x)=x^(2)+4x+5 is into

The function f : (0, oo) rarr [0, oo), f(x) = (x)/(1+x) is
