1.
Write each of the following in interval notation (Note: you may find it helpful to draw a number line):
-
\(\displaystyle x \ge -5\)
-
\(x \le -3\) or \(x \gt 6\)
-
\(\displaystyle x \neq 88\)
-
\(x \ge -2\) and \(x \lt 6\)
-
Everything except \(\pm 6\)
-
\(\displaystyle x \lt 18\)
-
Everything except \(0\)
-
\(x \lt -5\) or \(x \gt -5\)
Answer.
-
\(\displaystyle [-5, \infty)\)
-
\(\displaystyle (-\infty,-3]\cup(6,\infty)\)
-
\(\displaystyle (-\infty,88)\cup(88,\infty)\)
-
\(\displaystyle [-2, 6)\)
-
\(\displaystyle (-\infty,-6)\cup(-6,6)\cup(6,\infty)\)
-
\(\displaystyle (-\infty,18)\)
-
\(\displaystyle (-\infty,0)\cup(0,\infty)\)
-
\(\displaystyle (-\infty, -5)\cup(-5, \infty)\)
