What am I missing here? Since x is a neg integer, possible values for x are: 2,3,4,5 Least value for 2x  11: 2*(2)  11= 15 DavidTutorexamPAL , where did your post go? :D

A. 7 B. 5 C. 3 D. 1 E. 0 BunuelGiven that x is negative, 2x is negative and 2x  11 is larger than 11... Is there an error in the question? EDIT: As we're asked for the least possible value, we'll start from the smallest answer and work our way up. This is an Alternative approach. If (E) were true, than 2x + 11 = 0 meaning that 2x = 11 > x is not a negative integer. If (D) were true, than 2x + 11 = 1 meaning that 2x = 1+11 = 12 > x is not negative or 2x = 1  11 = 10 and x = 5. In this case x^2 = 25 so 2 < x^2 < 36 as required. (D) must be our answer.

A. 7 B. 5 C. 3 D. 1 E. 0 Least possible value of a mod function is 0 Here 0 can be attained by 2x+11 = 0 or x = 5.5, now since x^2 <36, x can't be 6 Hence at x = 5; the value of the function is 10+11 = 1 Hence D

A. 7 B. 5 C. 3 D. 1 E. 0 Given that x is a negative integer and and 2<x^2<36 so the values the X can take that satisfy this condition are 2, 3, 4,5 i.e 2< (2)^2 < 36 ; similarly for others Substituting the values of 2, 3, 4 and 5 in 2x+11 The lowest number would be when 2(5) + 11 = 1 Hence D

So, we are given that x is negative, and that square of x is between 2 and 36. That takes us to some possible values of x, such as 2,3,4,5. In order to minimize the modulus 2x+11 output, we need to maximize the negative value inside the modulus. That said, the biggest value of x inside the modulus would be 5.
In algebra... x = 5 2x+11 =?
2*(5)+11 = 10+11 = 1

2<x^2<36 X can be 2,3,4,5 We need to make 2x+11 as minimum , it's minimum value is zero For zero x need to be 5.5 which is not possible as his negative integer Then plugging values of 2,3,4,5 We get minimum value as 1 for x=5 Posted from my mobile device
