  • Q9
    What is the difference between the domain and the codomain of a function?
    The domain is the set of inputs that the function can accept, while the codomain is the set of all possible outputs.
    The domain and the codomain are the same sets in a function.
    The domain is the set of outputs that the function can produce, while the codomain is the set of all possible inputs.
    The domain is the set of input-output pairs, while the codomain is the set of all possible inputs.
