• Which of the following is not true of first-class objects?

  1. They can appear in expressions
  2. They can be assigned to a data type
  3. They can be assigned as arguments
  4. They can be returned in function calls

  2
• What name is given to the set of outputs from a function?

  Co-domain
• Which part of this type signature is the argument type: f: A -> B

  A
• What name is given to the set of inputs to a function?

  Domain
• What do functional programs use as first-class objects?

  Functions
• What name is given to the process of giving particular inputs to a function?

  Function application
• What must be true of two functions if they are to be combined?

  The domain of one of the functions must be the same as the co-domain of the other function.
