Exercise · ZW-FUNCTION-002 · ★☆☆ Basic
In \(f : A \to B\), what is the domain?
Choose one option.
Show answer
- C. A
Explanation
The domain of \(f : A \to B\) is \(A\), the set of allowed inputs. \(B\) is the codomain, and the image is the subset of \(B\) actually reached.
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.
\[f:A\to B\]
