Question

Graph the set {x|x≤-5} on the number line. Then, write the set using interval notation.

Answer 1

The interval notation that defines this set is: (-∞, -5]

And the graph can be seen below.

How to graph the inequality?

Here we want to graph the inequality:

x ≤ -5

This refers to all the values of x equal or smaller than -5.

To graph this, we need to graph a closed circle at -5, and we need to draw an arrow that points to the left (values smaller than -5). The graph is the one that you can see below.

The interval notation that defines this set is: (-∞, -5]

The first end is open, and the second is closed (because of the symbol ≤).
