Answer:
![10100](https://tex.z-dn.net/?f=10100)
Step-by-step explanation:
Use this formula,
![\frac{n}{2} (2 {a} + d(n - 1)](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%7D%7B2%7D%20%282%20%7Ba%7D%20%2B%20d%28n%20-%201%29)
where n is the amount of even intergers, a is the starting term, d is the common difference.
- the amount of even intergers from 2 to 200 is 100
- The starting number is 2
- The common difference is 2
![\frac{100}{2} (4 + 2(99)](https://tex.z-dn.net/?f=%20%5Cfrac%7B100%7D%7B2%7D%20%284%20%2B%202%2899%29)
![50(4 + 198)](https://tex.z-dn.net/?f=50%284%20%2B%20198%29)
![50(202)](https://tex.z-dn.net/?f=50%28202%29)
![10100](https://tex.z-dn.net/?f=10100)
No it is not a function, because a function cannot have more than one output per input. When x=-3, there are two solutions shown: (-3,2) and (-3,3), therefore it cannot be a function.
