Question

Which of the following sets would have a graph with an open circle on 2 and a ray pointing left on the number line?

O XIXERX 52)
OXIXER,X> 2)
O XIXER, X < 2)

Answer 1

x

Explanation:

Given

Open circle on 2

Arrow pointing left

Required

Determine the inequality

An open circle on 2 means represents either < or >

The arrow points to the left of -2 means that the number line represents numbers less than 2. i.e. < 2

Represent the numbers with x.

The inequality is: x < -2

Using proper notation, the inequality is: x∈ R, x < 2
