Answer :

Given the graph of Time Vs. Population, you can identify that the x-axis represents the Time (in years), and the y-axis represents Population (in thousands),

Notice that, in this case, when:

[tex]x=2[/tex]

The corresponding y-value is:

[tex]y=4[/tex]

And when:

[tex]x=1[/tex]

The y-value is:

[tex]y=6[/tex]

Therefore, you can identify that as the number of years decreases from 2 to 1, the population increases.

Hence, the answer is: First option.
