Daniel studied the characteristics of two different elements in his laboratory. The temperature, in degrees Celsius, of Element A, A(t), after t hours, is given by the function A(t) = 14(1.25)t. The temperature, in degrees Celsius, of Element B, B(t), after t hours, is given by the function B(t) = -2t2 + 18t + 2. Which function best describes the difference in the temperatures, C(t), for the two elements after t hours?
