Step-by-step explanation:
How does y change as x increases over a range?
As x increases from -6 to -4, y decreases from 0 to -7
It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant
As x increases from -4 to 0, y increases from -7 to 4
It is an increasing function in this range.
For x increasing from zero, y becomes less and less
It is a decreasing function in the range larger than x = 0

Answer:
Step-by-step explanation:
The terms of the sequence are:
We can rewrite the terms in factored form to get;
We can see that the subsequent terms are obtained by multiplying the previous term by . This is called the common ratio.
Therefore the first term of this geometric sequence is and the common ratio is
.
The nth term of a geometric sequence is given by: .
Let us substitute the first term, the common ratio, and to obtain:
