The temperature of a chemical solution, in degrees Celsius, is modeled by the function , where is the number of minutes after a cooling process begins. Which of the following is the best interpretation of ?
The temperature of the solution decreases by 4 degrees Celsius every 12 minutes.
After 4 minutes, the temperature of the solution is 12 degrees Celsius.
When the temperature of the solution is 4 degrees Celsius, 12 minutes have passed.
The solution cools down to 4 degrees Celsius in 12 minutes.
