Question

Which of the following sets would have a graph that is a closed circle on -4 and an arrow to the left?
{x | x ∈ R, x < -4}
{x | x ∈ R, x ≤ -4}
{x | x ∈ R, x > -4}
{x | x ∈ R, x ≥ -4}

Answer 1

closed circle mean that the value will be included in the set so you will need either\[\le or \ge\]

Answer 2

{x | x ∈ R, x ≤ -4}

Answer 3

To the left means you want values that are less than that value

Answer 4

so its the bottom one

Answer 5

no marvin is correct, remember your symbols \[\le\] is less than \[\ge\] is greater than
