The initial temperature of the coffee was 90°C.
Step-by-step explanation:
The function representing the temperature of the coffee after <em>x</em> minutes is:
T is the temperature in degree Celsius.
The initial temperature of the coffee will be at <em>x</em> = 0.

Answer:
YES
Step-by-step explanation:
