Exercise · ZW-FUNCTION-010 · ★★☆ Intermediate
If f is bijective, then there exists a function...
Choose one option.
Show answer
- C. inverse f⁻¹
Explanation
A bijective function is injective and surjective at once; then every element of the codomain has exactly one preimage, which allows defining the inverse function f⁻¹.
Review the concept: Function
A function f from A to B assigns to each element of A exactly one element of B. A is the domain and B the codomain.
\[f:A\to B\]
