A linear function \(\displaystyle \ \to \ \ \) f(x) = A*x +BFull question: A linear function exists such that f(x+2) - f(x) = 6. Determine the value of f^-1(x+2)-f^1(x)
Where I went wrong: I assumed the answer would be f^-1(8)-f^-1(6), but that's incorrect.
To clarify: f^-1(x) means inverse
One way to start is to observe the relationship between f(x+2) - f(x) = 6 and the slope of the linear function. From this, you can directly answer the question, with the same sort of thinking. What do you think the slope of the inverse function will be?Full question: A linear function exists such that f(x+2) - f(x) = 6. Determine the value of f^-1(x+2)-f^1(x)
