집합 A = {y = y = x & # 178; - 1, x * 8712 ° R}, B = {y | y = - 2x & # 178; + 2, x * 8712 ° R}, A 874 B 집합 A = {y = y = x & # 178; - 1, x * 8712, R}, B = {y = y = y = - 2x & # 178; + 2, x * 8712, R}, A ∩ B 집합 P = {y = 3x - 1, x & lt;;;;;;;;;;, Q = {/ y = - 2x & # 178; + 10, x * 8712, R}, P ∩

1 、
y = x & # 178; - 1 ≥ - 1
y = - 2x & # 178; + 2 ≤ 2
그래서 A ∩ B = {y | - 1 ≤ y ≤ 2}
2 、
x > 1, 즉 y > 3 - 1 = 2
y = - 2x & # 178; + 10 ≤ 10
그러므로 p ∩ Q = {y | 2 ≤ 10}
