Answer:
Step-by-step explanation:
I think it is a strangely worded question as they only refer to the larger gear turning.
I believe that this is what they are going for.
Number of teeth passing in each revolution
The Numbers match when the large gear turns two times as the smaller gear turns three times.
Since the function is even, its degree must be even (so it might be 2, 4, 6, ...)
In particular, all these numbers are one more than a perfect fourth power:
![(-3)^4=3^4=81 \implies f(-3)=f(3)=81+1=82](https://tex.z-dn.net/?f=%28-3%29%5E4%3D3%5E4%3D81%20%5Cimplies%20f%28-3%29%3Df%283%29%3D81%2B1%3D82)
![(-2)^4=2^4=16\implies f(-2)=f(2)=16+1=17](https://tex.z-dn.net/?f=%28-2%29%5E4%3D2%5E4%3D16%5Cimplies%20f%28-2%29%3Df%282%29%3D16%2B1%3D17)
![(-1)^4=1^4=81 \implies f(-1)=f(1)=1+1=2](https://tex.z-dn.net/?f=%28-1%29%5E4%3D1%5E4%3D81%20%5Cimplies%20f%28-1%29%3Df%281%29%3D1%2B1%3D2)
![0^4=0 \implies f(0)=0+1=1](https://tex.z-dn.net/?f=0%5E4%3D0%20%5Cimplies%20f%280%29%3D0%2B1%3D1)
So, the function is
![f(x)=x^4+1](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E4%2B1)
and the degree is 4.
