Indeed correct answer is E. I am still confused why |X| is not correct choice.
since X can take value from -3 to 5. Its a finite length of segment. Can you guys clear my confusion?

Inequality problem
Which of the following inequalities has a solution set that, when graphed on the number line, is a single line segment of finite length?
A. X power 4 >= 1
B. X power 3 <= 27
C. X power 2 >= 16
D. 2 <= |X| <= 5
E. 2 <= 3X + 4 <= 6
I choose D which is wrong. Can someone explain?

I am going with A) 17 Natural numbers start with 1 and there are 17 numbers(1-17) that are less than or equal to the square of 289 which is 17 Whats the OA? Given that [n1/2] = 17, it is necessary that 17 < n1/2 < 18. Squaring throughout, 289 < n < 324. Clearly there are 35 values of n (natural num...
