Set a = {y | y = x & # 178; - 1, X ∈ r}, B = {y | y = - 2x & # 178; + 2, X ∈ r}, find a ∩ B Set a = {y | y = x & # 178; - 1, X ∈ r}, B = {y | y = - 2x & # 178; + 2, X ∈ r}, find a ∩ b set P = {y | y = 3x-1, X & gt; 1}, q = {y | y = - 2x & # 178; + 10, X ∈ r}, find P ∩ Q

Set a = {y | y = x & # 178; - 1, X ∈ r}, B = {y | y = - 2x & # 178; + 2, X ∈ r}, find a ∩ B Set a = {y | y = x & # 178; - 1, X ∈ r}, B = {y | y = - 2x & # 178; + 2, X ∈ r}, find a ∩ b set P = {y | y = 3x-1, X & gt; 1}, q = {y | y = - 2x & # 178; + 10, X ∈ r}, find P ∩ Q

1、
y=x²-1≥-1
y=-2x²+2≤2
So a ∩ B = {y | - 1 ≤ y ≤ 2}
2、
x> 1, then Y > 3-1 = 2
y=-2x²+10≤10
So p ∩ q = {y | 2 ≤ y ≤ 10}
