Arelation contains the points (2, 4), (–9, 0), (–1, 7) and (2, –6). the relation is not a function. what x- or y-coordinate value could you change to make the relation a function?

We have to change the 'x' value of the point (2, -6) to 3 so the new point is (3, -6).

Step-by-step explanation:

Given:

The relation is given as:

{(2,4), (-9, 0), (-1, 7), (2, -6)}

The above set is not a function because the 'x' value of 2 has two images or 'y' values.

For

So, this is not a function as for a function each 'x' value should have a unique 'y' value.

In order to make the above relation a function, we need to change the 'x' value of either of the points (2, 4) or (2, -6). Let's change the point (2, -6). We change the value of 'x' such that it doesn't equals any of 'x' values of the given set. So, we can't take 'x' values as 2, -9, and -1. We can take any other value. So, let us take 3 as the value. So, the point becomes (3, -6).

Now, the given relation is a function as each 'x' value has unique 'y' value.

(2, 4), (-9, 0), (-1, 7) and (3, -6)

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
