Question

1. $x < 3$ 3. $xgeq4$

Explanation:

Step1: Identify inequality type for \(x < 3\)

It's a strict - less - than inequality. On a number line, we use an open circle at \(x = 3\) and shade to the left.

Step2: Identify inequality type for \(x\geq4\)

It's a greater - than or equal to inequality. On a number line, we use a closed circle at \(x = 4\) and shade to the right.

Answer:

For \(x < 3\), an open circle at 3 and shade left. For \(x\geq4\), a closed circle at 4 and shade right.
