If f A —> B and g : B —> C are injectivefunction, then gof: A —> C is an injectivefunction. Prove or disprove.
Question
Solution 1
This statement is true. Here is the proof:
Assume that f: A → B and g: B → C are injective functions. We want to show that the composition function g o f: A → C is also injective.
By definition, a function is injective (or one-to-one) if different inputs always produce different outputs. In other Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
