Bunnel , I didn't understand when the largest positive integer in the list is 7 , how did the range become 71 = 6 , shouldn't it be 7

A. 5 B. 6 C. 7 D. 11 E. 12 Solution: Set K = ( 4, 3, 2, 1, 0, 1, 2, 3, 4, 5, 6, 7) Range is defined as the highest value of f(x) and the lowest value of f(x). Over here the range will be 7  (4) = 11. Try making a graph of the set K and see what is the difference between the maximum value and the minimum value.

Try making a graph of the set K and see what is the difference between the maximum value and the minimum value. The set is {4, 3, 2, 1, 0, 1, 2, 3, 4, 5, 6, 7}. The question asks to find the range of the POSITIVE integers in the list. The range of the POSITIVE integers in the list is {largest}  {smallest} = 7  1 = 6. Hope it's clear.

Oh! I misread the positive numbers. Then the range is 7  1 = 6

5 6 7 11 12 Simple one. However, the only thing to notice in this question is " range of the positive integers". You miss this and you are gone

(A) 5 (B) 6 (C) 7 (D) 11 (E) 12
Can someone explain how to arrive at the OA? I am getting range of 11!! OMG!! totally need to pay attention to what Q is asking...yes...the OA is correct!

Answer Options:
A 5 B 6 C 7 D 11 E 12 numbers are 4,3,2,1,0,1,2,3,4,5,6,7 range of positive numbers = 71= 6 note: zero is neither positive nor negative. it is neutral.

Answer = B = 6 If least = 4, then largest = 7 Range = 7  1 = 6

so if it asks you for the positive and negative range then it would be 11 right? 7 (4)= 11? or do you get two answers one for positive and one for negative?

The set is {4, 3, 2, 1, 0, 1, 2, 3, 4, 5, 6, 7}. The range of the POSITIVE integers in the list is {largest}  {smallest} = 7  1 = 6. The range of the NEGATIVE integers in the list is {largest}  {smallest} = 1  (4) = 3. The range of the whole set is {largest}  {smallest} = 7  (4) = 11.
