Question

1. Write down the four inequality symbols and give an example to show what each one means.

Answer 1

The four inequality symbols are,

$<,>,\leq,and\ge$

The example for each one of inequality symbol are,

$x<4$

In this inequality, possible values of x are less than 4 (not including 4). x can takes all the values that are less than 4.

Second inequality,

$x>4$

In this inequality x takes all the value that are greater than 4 (not including 4). x takes all the values more than 4.

Third inequality,

$x\leq4$

In this inequality x takes all possible values of x less than 4 but also include 4. x can takes all the value less than or equal to 4. In this x can also be equal to 4.

Fourth inequality,

$x\ge4$

In this inequality x takes all possible value that are more than 4 and equal to 4 (It include 4 also). x can takes all values more than or equal to 4. In this inequality x can also be equal to 4.
