Question

What is x - 8 < -2 in set notation?

Answer 1

First, we need to solve for x. x < 6
Converting to set notation this becomes \[x: (-\infty, 6)\]

Remember that parenthesis indicate that x cannot equal the value, while square brackets indicate x can equal the value. For example, if we had\[x \le 6\]In set notation, this would be \[x: (-\infty, 6]\]
