Question

Help me please ill medal and fan

Answer 1

But we can assume there is a function f(x) such that:
f(1) = 11
f(2) = 20
f(3) = 34
f(4) = 41
So the ordered pairs will be: (1, 11), (2, 20), (3, 34) and (4, 41)
The justification is for each point in the domain: 1, 2, 3, 4 we have assumed a function that has one unique value in the range. So it is a function.

Answer 2

We can create another relation g(x) such that:
f(1) = 11 or 20
f(2) = 20
f(3) = 34
f(4) = 41

So the ordered pairs are: (1, 11), (1, 20), (2, 20), (3, 34), (4, 41)
Here g(x) is a relation but it is NOT a function because for the same value x=1, g(x) can can have two different values of y.
