The function `f: R->R` defined by `f(x)=4^x + 4^|x|` is

The function f:R toR defined by f(x) = 4^(x) +4^(|x|) is

The function f: R to R defined by f(x) = 4x + 7 is

State whether the function f : R rarr R, defined by f(x) = 3 - 4x is onto or not.

Prove that the function f: R to R defined by f(x) = 4x + 3 is invertible and find the inverse of 'f' .

The function f :R to R defined by f (x) = e ^(x) is

If the function f: R to R defined by f(x)=(4^(x))/(4^(x)+2), then show that f(1-x)=1-f(x), and hence deduce the value of f((1)/(4))+2f((1)/(2))+f((3)/(4)) .

Prove that the function f : R to R defined by f(x) = 3 - 4x , AA x in R is bijective.

If the function f:R rarr R defined by f(x) = 3x – 4 is invertible, find f^(-1)
