In cleaning toxic waste sites, typically the amount of waste eliminated per period decreases over time. That is, the amount of toxic waste remaining is decreasing at a decreasing rate. A graph of this function would be _____, becoming _____ over time.
A)decreasing; steeper
B)increasing; steeper
C)increasing; less steep
D)decreasing; less steep

Question

Quizplus · Accepted Answer

In the given scenario, the decrease in the amount of toxic waste per period is decreasing which means the rate of decrease is slowing down over time. This represents a negatively accelerating curve which is decreasing at a decreasing rate. Thus, the graph would be decreasing (as waste is eliminated) but becoming less steep over time. Therefore, option D is the correct choice.
