Question

What inequality is represented by this graph?

1 2 3
s 8 i å
6 7 8 9
X36
X x28

Answer 1

`x < 6`

Explanation:

Given

The attached plot

Required

The inequality

The arrow points starts at 6 and points left.

This means that:

`x < 6` or
`x \le 6`

The open circle on 6 implies that the inequality is either
`<` or
`>`

Hence,
`x \le 6` is invalid

So, the inequality is:
`x < 6`
