You can factor the 32 out of the sum:
We can also change the index as follows
Now, we have a theorem that states that the series
converges if and only if , and in this case we have
This is your case, because you have
which implies that your series converges, and the value is
Answer:
f(3) = -13
Step-by-step explanation:
To answer this question, we plug 3 into the place of x, so the equation now looks like;
f(3) = -5(3) + 2
We simply apply PEMDAS by multiplying -5 and 3, then adding 2 to get;
f(3) = -13
Hope this helps!
