The temperature change on the second day is greater than the temperature change on the first day.
<h3>What is temperature change?</h3>
The term temperature change refers to the difference in the temperature between the sunrise and the sunset. The temperature at sunrise and sunset are shown in the table attached to this answer.
The change in temperature on the first day is;
13.49 - (-11.31) = 24.80
The change in temperature on the second day is;
25.25 - (-7.69) = 32.94

In order to find zeroes of a function, we will probably want to use our quadratic formula.
-b±√b^2-4(a)(c)/2a
If we know our values, we can plug it in.
Our values:
A=1 (Since there is no number in front of x, it is an assumed 1)
B=17
C=72
Now, We can plug it into our formula.
BE SURE TO PUT PARENTHESIS AROUND ALL TERMS!
-(17)±√(17)^2-4(1)(72)/2(1)
Now we can type it into a calculator!
When we plug it into the formula. It gives us two real solutions (or zeroes) which are represented as:
-8 & -9.
