The energy in a rechargeable battery is changing with respect to time, such that the energy is given by C(t), where C(t) is measured In Coulombs and t is measured In seconds. A tangent line is shown for C(t) at t = 4 seconds. Determine the best estimate for the value of the Instantaneous rate of change of C(t) when t = 4.
