Question

Harry 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 notation \( f(10) = 120 \) indicates that after 10 minutes of cooling, the temperature of the coffee is 120 degrees Fahrenheit. This means that if you were to measure the coffee's temperature exactly 10 minutes after it was poured, you would find that it has cooled down to 120°F.
