Which of the following inequalities has a solution set that, when graphed on the number line, is a single line segment of finite length.
x^4 >or equal to 1
x^3 <or equal to 27
x^2 > or equal to 16
2 <or equal to abs value of x <or equal to 5
2 <or equal to 3x + 4 <or equal to 6
The answer is E. Could anybody tell me what's the best approach to this question?
