Question

Daniel poured a cup of hot coffee and let it cool. The temperature of the coffee after x minutes is given by the function f(x). The temperature is measured in degrees Fahrenheit.
What does f(10)=120 tell you?

Answer 1

The expression \( f(10) = 120 \) indicates that after 10 minutes, the temperature of the coffee is 120 degrees Fahrenheit. This gives us specific information about the cooling process of the coffee, showing that it has cooled down to that temperature at the 10-minute mark.
