f(x) where x belongs to all real numbers(adsbygoogle = window.adsbygoogle || []).push({});

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 im not really sure if thats right :s
