Picking number
a=-1/2
q=1/2-1=-1/2
r=1/4
s=-1/8
so on the number line, we do have q < s < r
B is the answer
a=-1/2
q=1/2-1=-1/2
r=1/4
s=-1/8
so on the number line, we do have q < s < r
B is the answer

Given - 1 < a < 0
q = a−1 < a
r = a^2 --> a > 0
s = a^3 --> a < s < 0
So, q < a < s < r
Answer B
q = a−1 < a
r = a^2 --> a > 0
s = a^3 --> a < s < 0
So, q < a < s < r
Answer B
