Answer:
Tn=13n-18
Step-by-step explanation:
Tn=-5(n-1)13
Simplify
this is using the a+(n-1)d
we know that
The domain of the function are the values of x for which the function exists and the range of the function are the values of the function
in this problem
The domain of the function are the values 
The range of the function are the values 
therefore
<u>the answer is the option B</u>

Answer:
- 23
Step-by-step explanation:
We could do this the long way and expand the whole product or note that the
terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is
4a³ × 3a = 12
+ 5a² × - 7a² = - 35
Summing gives
12
- 35
= - 23
with coefficient - 23
