Average daily temperature on the first day of each month for one year.

Use the graphing calculator to graph the data points. Use 0 for January, 1 for February, 2 for March, and so on.

Sure, let's go through this step-by-step:

1. Understanding the Data:
- The data represents the average daily temperature on the first day of each month for one year.
- We will use the numbers 0 through 11 to represent the months January through December respectively.

2. Data Points:
We can organize the data into two arrays: one for the months and one for the corresponding temperatures.

| Month | Temperature (°F) |
|------------|-------------------|
| January (0) | 23 |
| February (1) | 35 |
| March (2) | 48 |
| April (3) | 65 |
| May (4) | 74 |
| June (5) | 80 |
| July (6) | 76 |
| August (7) | 64 |
| September (8)| 50 |
| October (9) | 32 |
| November (10)| 24 |
| December (11)| 20 |

3. Preparing to Graph:
- On the x-axis, we will have the months indexed from 0 (January) to 11 (December).
- On the y-axis, we will have the temperatures measured in degrees Fahrenheit (°F).

4. Plotting Data Points:
- Mark the data points on the graph where the x-coordinate is the month and the y-coordinate is the temperature.

Here's a basic plot of the points:

--------------------------------------------
0 1 2 3 4 5 6 7 8 9 10 11
```

5. Connecting the Points (Optional):
- You may draw a line or smooth curve connecting these points to visualize the trend over the year.

6. Analysis:
- From the graph, we notice that the temperatures generally increase from January (0) to June (5), peak in June, and then decrease towards December (11).

If you are using a graphing calculator, you can input these points manually and then plot them to see the trend over the year. Make sure to label the axes appropriately and connect the points to show the changing temperature through the months.
