Question

Which graph represents the compound inequality?n < –2 or n ≥ 4

Answer 1

The correct graph is in the picture below

Answer 2

we have

`n < -2` -------> inequality A

The solution of the inequality A is the interval------> (-∞,-2)

All real numbers less than
`-2`

`n\geq 4` -------> inequality B

The solution of the inequality B is the interval------> [4,∞)

All real numbers greater than or equal to
`4`

The solution of the compound inequality A or B is equal to

Solution A+Solution B

(-∞,-2) U [4,∞)

therefore
