Quick algebra 1 question for 25 points!<br><br> Only answer if you know the answer, Tysm!

Using a quadratic regression equation, it is found that the prediction of volunteers in year 10 is of:

A. 47.

<h3>How to find the equation of quadratic regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

In this problem, we have that the function initially increases, then it decreases, which means that it is a quadratic function. The points (x,y) to  be inserted into the calculator are given as follows:

(1, 20), (2,17), (3, 16), (4,16), (5,18), (6,21), (7,25), (8,31)

Inserting these points into the calculator, the prediction of y for a value of x is given as follows:

y = 0.702x^2 - 4.726x + 23.857

Hence, when x = 10, the prediction is:

y = 0.702 x 10² - 4.726 x 10 + 23.857

y = 47.

Hence option A is correct.
