<em>Assuming [x] means the closest integer to x</em>
Answer:
Step-by-step explanation:
We can see that for any integer 
, there will always be a ![[x]](https://tex.z-dn.net/?f=%5Bx%5D)
, so there will always be a ![[x]+1](https://tex.z-dn.net/?f=%5Bx%5D%2B1)
. So, we don't need to worry about the domain impacting the range.
can be any integer from 
to 
, and as 
(at least in terms of a function's range and domain), the range of is equal to the range of , which is .
So, the answer is 
and we're done!
Answer: do the reciprocal
Step-by-step explanation: flip it
2x^4+x^3-x^2+8x^2+4x-4=2x^4+x^3+7x^2+4x-4
