The Relation (2,11) , (a,15) , (5,22) , (7,30) is not function if a = 22
11
7
which one

7

Step-by-step explanation:

Greetings.

The answer is 7.

Explanation:

Function is a set of relation with domains that are not repetitive. What I'm trying to say is that in a single set, there cannot be same domain values.

For example,

(1,2) (1,3)

The relation above is not a function since the domain is repetitive (There are two 1's as domain which is not a function.)

But If it is (1,2) (2,1) (3,1) Then It's a function. Because there are no repetitive domains.

The question asks you which value would give the whole set only a relation and not a function.

As explained, 2 repetitive, same domains don't make the relation a function, but rather a relation instead.

Hope this helps! :)

Feel free to ask anything in the comment/reply if you are curious/confused with Function.

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
