How do I make a function that takes user input and returns a list containing n copies of input?

So it starts off with something like this...

(define (duple n x)

(...))

Now how would I proceed with this?

Solving for the function above would allow the test cases to run.

An example:

(test (duple 5 '(hey))

and it should output '((hey) (hey) (hey) (hey) (hey)))

any form of help has to be in racket with plait language only! Thanks.
