Question

Below, you are given a mapping diagram.

Answer 1

Create and justify a relation that represents a function with the given range. Write your answers as ordered pairs.

Create and justify a relation that does not represent a function with the given range. Write your answers as ordered pairs.

Answer 2

Answer 3

I don't know :/

Answer 4

As long as you use enough X's to pair with the y's (they can be used more than once) you'll have a function. WHen you are doing the range, that is really called ONTO and you are trying to do the same thing... Name enough y's so that they are not being used more than once.

Answer 5

Not sure what they want.

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 6

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.
