Question

The solution to an inequality is given in interval notation as (2, ∞). What is another way to represent this solution set?

A number line going from negative 5 to positive 5. A solid circle appears at positive 2. The number line is shaded between positive 2 and negative 5.
A number line going from negative 5 to positive 5. An open circle appears at positive 2. The number line is shaded between positive 2 and negative 5.

Answer 1

The last option.

(2, ∞) means all numbers greater than 2, not including 2 — so use an open circle at 2 and shade to the right (toward +5 and beyond).
