Question

Solve |x| > 3
{-3, 3}
x
x < -3 ∩ x > 3

Answer 1

Answer: Second Option

x

Explanation:

To solve the inequality

`| x | >3` there are two cases:

Case 1.
`x>0`

`x > 3`

Case2.
`x<0`

`-x > 3`

`x < -3`

The final solution is the union of the solution of each case

This is:

`x < -3` or
`x > 3`

x< -3 ∪ x > 3
