Hello.
00:01
So here we are asked, can we return more than one value from a function? well, the answer to that is going to be no.
00:10
So what is a function? well, your function basically is a relation between a two sets, set of inputs and set of outputs, where we have that every input has to have exactly one output.
00:23
So we could think of a function as a relation between two sets.
00:28
Then we could have the sets.
00:29
Could be infinite.
00:30
We could just have a finite number of things.
00:32
So here we have our, let's say, one set is going to be our set a.
00:36
And then we have another set.
00:37
So we have our domain.
00:39
Then we have our codomain.
