**Experiment: Temperature Change of a Soda Can**

(b) A cold can of soda is removed from a refrigerator. Its temperature \( F \) in degrees Fahrenheit is measured at 5-minute intervals, as recorded in the following table, thus defining \( F \) as a function of \( t \) (in minutes).

\[
\begin{array}{|c|c|c|c|c|c|c|c|}
\hline
t & 0 & 5 & 10 & 15 & 20 & 25 & 30 \\
\hline
F(t) & 37.00 & 44.74 & 50.77 & 55.47 & 59.12 & 61.97 & 64.19 \\
\hline
\end{array}
\]

**Analysis Questions:**

1. Is \( F \) always increasing or always decreasing? What does that tell us about the soda?

2. Is \( F \) always concave up or always concave down? What does that tell us about the soda?

---

**Explanation of the Table:**

- The table shows the temperature \( F \) of the soda can at different times \( t \) after removal from the refrigerator. 
- It starts at a temperature of 37.00°F at 0 minutes and increases to 64.19°F at 30 minutes. 

This experiment helps understand the rate of temperature change and the behavior of the soda's temperature as it adjusts to room temperature over time.
