Mathematics for IGCSE & O level - Functions (Section 1 - No. 15)
Which of the following is not true about the inverse function?
The inverse function is denoted as f^-1(x).
The inverse function reverses the process of the original function.
The domain of the inverse function is the same as the domain of the original function.
If (a, b) is a point on f(x), then (b, a) is a point on f^-1(x).
Vysvětlení
The domain of the original function becomes the range of the inverse function.
