Question

Which of the following statements says that a number is between -3 and 3?Olx = 3Olx <3Olx > 3

Answer 1

If |x|=3, then x can either be 3 or -3.

If |x| < 3, then x < 3 or -x < 3. Multiplying -1 on both sides of the second inequality, we have the following.

$\begin{gathered} x<3 \\ \\ x>-3 \end{gathered}$
