Given the arithmetic sequence an = −5 + 3(n − 1), what is the domain for n?
2 answers:
Answer:
Domain for n is All integers where n ≥ 1.
Step-by-step explanation:
Given the arithmetic sequence
In arithmetic sequence,
where a is first term.
d is common difference.
n is number of terms.
Now, in given sequence recursive formula for nth term is
the number of term is n and it belongs to natural number.
Hence, domain for n is All integers where n ≥ 1.

Possible rational zeros are:
Step-by-step explanation:
We need to list all possible zeroes of the function using rational zero theorem.
The rational zero theorem.
rational zero theorem states that zeros can be found by dividing the factors of constant term called p by the factors of the leading co-efficient called q i.e
p/q
In our given function
p = 7
q = 5
Factors of p (7) = ±1, ±7
Factors of q (5) = ±1, ±5
So, possible rational zeros are:
