Answer:

1) 21

2) 28

3) 13

Step-by-step explanation:

Now, we just plug in the numbers.

14 + 7 = 21

7 ⋅ 4 = 28

5 ⋅ 4 - 7 = 13

kakasveta [241]

Answer:

Yes.

Step-by-step explanation:

If you write out the coordinates, you can see that you can do the Vertical Line Test and confirm that if you were to write a function, it would be an actual function. No 2 x-values can be the same y-values. The coordinates all have separate xy values (or the same exact xy values) and you can determine a function.
