  • Failing to specify the domain and codomain when defining a function or relation.

  • Confusing the concepts of injective (one-to-one) and surjective (onto) functions.

  • Assuming that every function has an inverse, without considering conditions like subjectiveness.

  • Using values outside the domain when evaluating functions or relations.

  • Misrepresenting relationships between sets using Venn diagrams.

  • Not using correct symbols (e.g., ∪, ∩, ⊆, etc.) when working with sets.

  • Forgetting to check whether a relation is reflexive or symmetric when required.
