ConceptRepresentation of Solution on the Number Line

#### Question

The diagram represents two inequations A and B on real number lines:

1) Write down A and B in set builder notation/

2) Represent A ∪ B and A ∩ B' on two different number lines

#### Solution

1) A = {x ∈ R: -2 ≤ x < 5}

B = {x ∈ R: -4 ≤ x < 3}

2) A ∩ B = {x ∈ R: -2 ≤ x < 5}

It can be represented on number line as:

B’ = {x ∈ R: 3 < x ≤ -4}

A ∩ B’ = {x ∈ R: 3 ≤ x < 5}

It can be represented on number line as:

Is there an error in this question or solution?
