The volume of a swimming pool is changing with respect to time, such that the volume is given by W(t), where W(t) is measured in cubic centimeters and t is measured in seconds. A tangent line is shown for W(t) at t = 3 seconds. Determine the best estimate for the value of the instantaneous rate of change for W(t) when t = 3. ΔW(t) / 3 W(3.1)-W(2.9) / 0.2 W(3)-W(0) / 3 W (limit of t as t approches 3)
