Our function is a graph, but it could have been a table of values or a formula. The graph illustrates that the temperature in degrees Celsius is a function of the temperature in degrees Fahrenheit. The temperature in degrees Fahrenheit, $F\text{,}$ is the input while the temperature in degrees Celsius, $C\text{,}$ is the output. Use the graph to estimate your answers below:

1. The temperature of $77$ degrees Fahrenheit to degrees Celsius
   $C=$
2. What temperature in Fahrenheit is the same as $-22$ degrees Celsius? (Type your answer as “$F=\ldots$”.)
