Question

The following number line represents:

Options

• {x : x ∈ R and x = 10}

• {(x < 10) ∪ (x > 10)}

• {(10 > x) ∩ (x > 10)}

• {x : x ∈ R and x < 10}

Answer 1

{(x < 10) ∪ (x > 10)}

Explanation:

Since the solution set contains the whole real line except x = 10

∴ Solution set = {(x < 10) ∪ (x > 10)}
