The critical points of a rational inequality are negative 1 , 3 , and 4 Which set of points can be tested to find a complete solution to the inequality?

The critical points −1, 3, and 4 divide the number line into four intervals: (−∞, −1), (−1, 3), (3, 4), and (4, ∞). To determine the inequality’s sign throughout, test one point in each interval. Choice B gives −3, 1, 3.5, and 5, with one point in each interval.
