Answer:
Step-by-step explanation:
We have a geometric sequence with:
, , and
Where
Sn is the sum of the sequence
r is the common ratio
is the first term in the sequence
n is the number of terms in the sequence
The formula to calculate the sum of a finite geometric sequence is:
Then:
Now we solve for
Wouldn't the formula be a×b/2?
I think maybe the second one I’m not fully sure but I hope this might help
Answer:
C) (-6,0)(2,0)
For x-intercept, f(x) = 0:
