They have volunteers and many weather stations places all over a region. They get many reports all throughout the day and update the information accordingly. They use recorded data to determine the highs and lows for a specific region for a specific date, which is why they report record highs and lows for an area as well. Some of these records date back 125 years or more. Today, they have computer models that tell them.
A line on a weather map that connects places where the temperature is the same is called an isotherm.
It is hot, but that says nothing about humidity, precipitation, cloud cover - all of which are relevant.
For common weather measurements Fahrenheit is used in the US. For scientific purposes both the Fahrenheit and the Celsius scale are used.
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.

Surface temperature information comes from a network of primarily automated weather stations. Upper air data come from 12-hourly weather balloons (radiosondes) and numerous remote sensing inputs.
Satellites. 2nd answer: There is a network of weather reporting stations in the US - many of them at airports - who report temperature, visibility, dew point, wind strength and direction, barometer readings, and so forth to the National Weather Service. Using this information, along with satellite photos and RADAR readings, they draw up and analyze weather maps.
