Answer:
The greatest value is q-n
The smallest value is n-q
q is closest to 0
Explanation:
The further to the left we go, the more negative it gets
n < q
from looking at the graph
n<q
Subtract q from each side
n-q < q-q
n-q < 0
This is less than 0
Now subtract n from each side
n<q
n-n < q-n
0 < q-n
This is greater than 0
Lets compare n-q and q
n = -4
q = -1
n-q = -4 --1 = -4 +1 = -3
-3 < -1
n-q < q
Lets look at q-n
-1 --4
-1 +4 = 3
q is closer to 0 than q-n
The greatest value is q-n
The smallest value is n-q
q is closest to 0
