Question

Kelsey, a marine biologist, has determined that the population (y) of Blue Whales off the coast of Antarctica varies with time, in months, (x). The population changes have been mapped using the graph below. What is the range of the population of Blue Whales off the coast of Antarctica from months 0 to 10?

Answer 1

Answer: The answer is (A) [0,100].

Step-by-step explanation: Given in the question that a marine biologist Kelsey determined that the population of Blue Whales off the coast of Antarctica varies with time as shown in the given graph.

The population of Blue Whales (y) is plotted on the Y-axis and the time in months (x) is plotted on the X-axis.

We need to find the range of the population of Blue Whales off the coast of Antarctica from 0 to 10 months.

We can see from the attached graph that

when x = 0, then y = 0,

when x = 10, then y = 100.

That is, when time varies between 0 to 10 months, then the population of Blue Whales varies between 0 and 100.

Thus, the correct option is (A) [0,100].
