Answer:
1x² + 1x -3
Step-by-step explanation:
A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
To compute manually the values of a, b and c is a rather complicated process using a technique known as least squares method.
However, we can use a scientific calculator to compute the three values and arrive at the quadratic equation
Using the points provided, the values are:
a = 1, b = 1, c = -3
The function is 1x² + 1x -3
Note that this is a best-fit function it does not necessarily pass through all 3 points but approximates. The attached graph shows that the function does indeed pass through 2 of the 3 points
Answer:
Cite in text the first few words of the reference list entry (usually the title) and the year. Use double quotation marks around the title or abbreviated title.: ("All 33 Chile Miners," 2010). Note: Use the full title of the web page if it is short for the parenthetical citation.

Answer:
The average change is 405
Step-by-step explanation:
The initially the number of subscriber = 12125
After five years the number of subscriber = 10100
Now we have to find the average change in the number of subscribers.
The average yearly change = change in subscriber/number of years.
Now insert the values in the above formula.
The average yearly change = (12125 – 10100) / 5
The average yearly change = 2025/5
The average yearly change = 405
