A. this is not a function because x=1 has 2 outputs So does x=3
B . f(120) = 20 + 10*120 = 1220

EXPLANATION
The terms of the given sequence are:
![26,10,-6,-22,...](https://tex.z-dn.net/?f=26%2C10%2C-6%2C-22%2C...)
The first term of this sequence is
![a_1=26](https://tex.z-dn.net/?f=a_1%3D26)
The common difference is
![d = 10 - 26 = - 16](https://tex.z-dn.net/?f=d%20%3D%2010%20-%2026%20%3D%20%20-%2016)
The nth term of this sequence is;
![a_n=a_1+d(n-1)](https://tex.z-dn.net/?f=a_n%3Da_1%2Bd%28n-1%29)
![g(n)=26 - 16(n-1)](https://tex.z-dn.net/?f=g%28n%29%3D26%20-%2016%28n-1%29)
This is the same as Vera's formula,
If we expand, we get,
![g(n) = 26 - 16n + 16](https://tex.z-dn.net/?f=g%28n%29%20%3D%2026%20-%2016n%20%2B%2016)
This simplifies to,
![g(n) = 42- 16n](https://tex.z-dn.net/?f=g%28n%29%20%3D%2042-%2016n%20)
This Feynyang's formula
What is h?
maybe 25%
i hope it helped you sorry if it didn't
