Ответ:
Example:
(4,2),(2,2),(12,0), (9,1) etc.
Ordered pairs consist of input (x) values and output (y) values. In the example (4,2), four would be the x or input value. 2 would be the y or output value.
Once you understand that, all you need to do is look at YOUR specific relation. Look at all the x values in your relation. Are there two of the same input values? If this is the case, your relation is NOT a function. That's how easy it is :)
Ответ:
The graph that has the points (2,4) and (4,8) should be the answer.
Step-by-step explanation:
This is the answer because if you see the ratio 2:4, that means that for every 2 offense cards there are 4 defense cards. As you continue to go up it would be (4,8), (6,12), (8,16), and so forth.
