Quizplus · Accepted Answer

There are no equal signs in the inequality, so we use a curved parenthesis to indicate that 3 is not included in the solution set. The solution set is all numbers greater than 3, so we use an infinity symbol to indicate that the solution set goes on indefinitely to the right. The interval notation is (3,∞). The correct choice is C. The solution set is from -infinity to -4, and from 6 to infinity. This can be written in interval notation as (-infinity, -4) U (6, infinity), which matches option C.
