The function which is used to represent the graphed geometric sequence is

Let a be first term and r common ratio of the Geometric progression.
The Geometric sequence is of the form a,ar,ar^2, ...
The common ratio will be ar/a.
From the graph, we can find out the sequence as 80,20,5, ...
Here we can see that the sequence is in Geometric Progression.
First term a=80
Common ratio r= ar/a
= 20/80
=1/4
General term of Geometric sequence is

Substituting the value a = 80 and r = 1/4,
we get,

Hence, the correct answer is

Answer:
7 to the 12th power. (The last one.)
Step-by-step explanation:
When dividing expressions with the same base you need to subtract the powers. In this case subtract 2 from 14 which makes 12. So your answer will be <u><em>7^12</em></u>.
Your numbers will be 3+2+3=8
If you try the hint, the first number minus the 2nd plus the third is 4 then: 3-2+3=4
Answer: 3+2+3=8
On the first play the Tigers lost yards. The number of yards they lost was 3 yards. We know this because the integer that is shown is -3. This negative value is move to the left or down on the number line. It represents a negative change, and in football it is a loss of yards.
