To find the answer, we plug 8 into the equation in the place of x, since x represents the number of minutes.
w(8) = 250(8)
2(8) = 2000
You can read 2000 words in 8 minutes.
.8, 1.8, 8, 8.1
Do you understand why? This seems pretty simple that you should be able to solve this for yourself.
It is A.) or the top left answer.
As shown in the figure below the answer is the last option:

The roots of the polynomial in the denominator are:


So, the inequality can be written as follows:

From this inequality we can study the signs and get the same conclusion just as shows the graph.
