f(x) where x belongs to all real numbers
inverse: f-1(x), where x belongs to all real numbers
True or False:
The inverse of f(x+3) is f-1(x+3)
My ideas:
I think that it is false given that when you usually find the inverse of a function, you switch the x and y variables and solve for y again meaning that the inverse couldn't stay the same.
I figured since the domain and range of f(x) belong to all real numbers, possibly f(x) = x and then inputting f(x+3) = x+ 3
then y = x+3
then y = x - 3 but I am not really sure if that's right :s
