Answer: an = -3 · 2^n - 1
Step-by-step explanation:
In a geometric series, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1 × r^(n - 1)
Where
a1 represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
Looking at the given sequence,
a = - 3
r = - 6/ - 3 = 2
Therefore, the formula for the sequence is
an = - 3 × 2^(n - 1)

Answer:
1) Function
2) Function
3) Not a Function
Step-by-step explanation:
Using the vertical line test, using a pen, pencil or finger to move it vertically, I determined that 2 of the 3 questions was a function because the last question would not be a function since there are two lines instead of one when doing the test. Hope this helps!
