Question

graph to show the solutions for: x < 4. click on the line to identify the endpoint.

Explanation:

Step1: Identify the inequality

The inequality is $x < 4$.

Step2: Determine the endpoint

The endpoint is $x = 4$. Since it is a strict - less - than inequality ($<$), we use an open - circle at $x = 4$ on the number line.

Step3: Shade the solution region

We shade the region to the left of $x = 4$ on the number line to represent all values of $x$ that satisfy $x < 4$.

Answer:

On the number - line, place an open - circle at $x = 4$ and shade the line to the left of $x = 4$.
