The critical points of a rational inequality are x is equal to negative 4 and x is equal to 2 Which set of points can be tested to find a complete solution to the inequality?

The critical points −4 and 2 divide the number line into three intervals: x < −4, −4 < x < 2, and x > 2. To find where the rational inequality is true, test one point inside each interval. The values −5, 0, and 3 do that, so the correct choice is D, x = −5, x = 0, and x = 3.
