are all types of object-oriented programming (OOP) languages.
the correct definition of a programming paradigm?

Haskell and Lisp are both types of what programming paradigm?
*
functional programming languages.
If the domain of the function below is {1, 2, 3}, what is the co-domain?
func x = x * 3
{3, 6, 9}
What is the correct term for using one function as an argument for another function?
Composition of functions
what is meant by a variable that is immutable?
Variables cannot be reassigned once they are given a value
characteristics of a first class object
Functional programming is stateless and has no side effects. what this means?
The state of memory does not change, i.e. the values of variables stay the same. Therefore there is no record of previous operations and each operation is processed using only the arguments/parameters provided will always return the same result for a given input and so cannot affect other operations within the program.
what is the head of a list [1.2.3]
what is the remainder
[1]
[2,3]
what does 5:[1,2,3] do
creates a new list with 5 at the front
concat[“fish” “and” “chips”] what does this do
creates a concatenated string of the elements in the list.
what does [1,2] ++ [3,4]

Which of the following is the correct definition of a higher-order function?

What does the map function do
a higher-order function that applies a given function to each item in an iterable
What is the filter function
A filter function takes a predicate function and a list, and it returns a new list containing the elements that satisfy the predicate.

what does the fold function do
