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)

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

goog may be able to you find that answer
