Types of Functions - A.I For Your Classroom

Injective: If \( f(a_1) = f(a_2) \), then \( a_1 = a_2 \) for all \( a_1, a_2 \in A \).
Surjective: For every \( b \in B \), there exists at least one \( a \in A \) such that \( f(a) = b \).
Bijective: The function \( f \) is both injective and surjective.
