Answer:
All real numbers
Step-by-step explanation:
You could approach this monstrosity using Pascal's Triangle, you could probably do something with Binomial Expansion/Binomial Theorem, and Synthetic Division works too I believe but that's gonna take up more space and time.
I used Pascal's Triangle to show my work. Doing that we see that this whole thing is just (x-1)⁶. And since 6 is an even power, any negative inside will reduce themselves out. This means that any number you put into the function will be greater than or equal to (at x=1) zero.
So all real numbers is your answer.
