Imagine a scenario involving a bungee jumper leaping from a bridge, with the jumper's height above the river surface modeled by the equation h(t) = -7t2 + v0t + h0, where h is measured in meters, t is in seconds, v0 represents the jumper's initial velocity in meters per second, and h0 is the initial height above the river. Given v0 = 0 m/sec and h0 = 20m.
(a) What is the domain and range of h(t)? What is the physical significance of domain and range in this scenario?
