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.
A) ![C(4)-C(0)/4](/tpl/images/2470/2359/df608.png)
B)Δ![C(t)/4](/tpl/images/2470/2359/e840c.png)
C) ![C(4.2)-C(3.8)/0.4](/tpl/images/2470/2359/d6d44.png)
D) C(lim t) t⇒ 4
