Answer:
"all integers from 1 to 5, inclusive"
Step-by-step explanation:
Domain is the set of x values (input) can makes the function defined.
Thus, we need to find which values can we put into the function, so that the output is valid.
Now,
f(x) = 500x + 45
This tells us that there are initially "45" sheets and more can be modeled using "500x" which says that x reams multiplied by 500 sheets per ream.
So , we understand that x is the number of ream of paper available.
Looking at the problem, we see that the store has 5 reams of paper.
Hence, the domain can be 1 ream, 2 ream...5ream
So, that 1 to 5, inclusive (integers, not real numbers)
