Which of the following sets would have a graph with an open circle on 2 and a ray pointing left on the number line?
{x | x ∈ r, x ≤ 2}
{x | x ∈ r, x > 2}
{x | x ∈ r, x < 2}

Hi, the graph you describe represents all real numbers smaller than 2, without the two (that's why there's the open circle). Hence the correct answer is the third choice {x | x ∈ R, x < 2}.
