You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h (20) = -6x + 330, where is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercepts of the graph.
