State the inputs and outputs of the following relation. Is it a function? { ( 2 , 5 ) , ( 0 , 2 ) , ( 2 , 9 ) \left(2,5\right),\left(0,2\right),\left(2,9\right) ( 2 , 5 ) , ( 0 , 2 ) , ( 2 , 9 ) }

let's see if we can solve this problem. In this problem, we are told to see the inputs and outputs of the following relation, which looks like this. We're also asked to determine whether or not this relation is an example of a function. Now what I'm first going to do is list out all of the inputs or x values and all of the outputs or y values for this relation. Now the x values correspond to the first coordinates that we have, and doing this in ascending order, I see that we have 2 and then we have 0. Actually, I should start with 0 because that's lower, and then we have 2. And I noticed that we have 2 twice, but I'm only gonna write it once in this bubble here. So these are all the inputs that we have. Now as for the outputs, these are going to be all of the y values or coordinates that we have here. We'll start with 2, that's one of the y values. We also have 5, and then we have 9. So these are going to be the outputs and the inputs. Now to figure out how these are related, well, let's take a look at these points. So So we can see here based on this point that 2 is related to 5. We can see from this point that 0 is related to 2, and we can see from this point that 2 is related to 9. Now is this an example of a function? Well, for something to be a function, each input can only have one output. And notice that we actually do break this rule, because this 2 here is related to 5, but it's also related to 9. We have an input with more than 1 output, And because this happens, we would say that this is not a function. So whenever you see an input which has multiple outputs, then it is not an example of a function. So this is the relation, and it's not a function. Hopefully, you found this helpful.

State the inputs and outputs of the following relation. Is it a function?
{ $\left(2,5\right),\left(0,2\right),\left(2,9\right)$ }

Input and Output Sets

Verified step by step guidance

Identify the given relation: {(2,5), (0,2), (2,9)}.

List the inputs (domain) from the relation: {2, 0}.

List the outputs (range) from the relation: {5, 2, 9}.

Determine if each input is associated with exactly one output. Notice that the input '2' is associated with two different outputs: '5' and '9'.

Conclude that the relation is not a function because an input (2) is associated with more than one output.
