One way in which the study of populations ( human populations - I assume) affects us is that they can help predict the population size in the future and prepare us for it.

To graph this inequality, start with an open dot on -2.
We use an open dot because n is
greater than -2 but n is not equal to -2.
Next we draw an arrow to the right

I have graphed this inequality below too.
The graph below is my own work.
This should correspond to the first answer choice.
