The <em>correct answer</em> is:
b.) –0.507x2 + 14.907x – 36.131
Explanation:
First we enter the data into a graphing calculator. The times are the x-coordinates and the temperatures are the y-coordinates; this is because temperature is dependent upon time.
After we enter this, we run a regression on the calculator. We will run the quadratic regression; the equation is of the form
y = ax²+bx+c.
The values we are given on a Casio fx-9860 gii are:
a = -0.507
b = 14.908
c = -36.136
This is closest to choice B.
