I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
1. 15-x
2. 4y
These are algebraic expressions for both.
We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:

Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:

On plotting the series, the result will be like this:
Exact Form - 5/12
Decimal Form - 0.41666666...
<h3>Hey Mate,.</h3>
<h3><u>Answer :- </u></h3>
• 1 / 3
<h3><u>Explanation :- </u></h3>
<u>As </u><u>we </u><u>know</u><u> </u><u>that </u><u>,</u><u> </u>
If a dilation produces a smaller figure then ,
0 < Scale factor < 1 .
So then ,
Case 1 ) -2 => The scale factor must be a positive number .
Case 2 ) 1 / 3 => 0 < 1/3 < 1 => Is a possible scale factor .
Case 3 ) 1 => This scale factor does not produce a smaller figure , It produces the same figure .
Case 4 ) 4 => This scale factor produces a larger figure .
<h3>• Hence, the answer is 1/3 .</h3>
