Question

If P = { x : -3 < x ≤ 7, x ∈ R} and Q = { x : - 7 ≤ x < 3, x ∈ R} , represent the following solution set on the different number lines : 

P ∩ Q

Answer 1

P = { x : -3 < x ≤ 7, x ∈ R}   and Q = { x : - 7 ≤ x < 3, x ∈ R}

P = {-2, -1, 0, 1, 2, 3, 4, 5, 6, 7} and Q = {-7, -6, -5, -4, -3, -2, - 1, 0, 1, 2} 

(i) P ∩ Q

P ∩ Q = {-2 , -1 , 0 , 1 , 2}
