The circle on the left is open, so it doesn't include x = − 2. x=-2. The line extends off to the right, including all of the numbers greater than − 2. -2. Thus, the answer is x > − 2. x>-2.

On my Note 4, the circle appears to include -2 and does not appear open.

I disagree, it's not readable. You should have taken a bracket " ] " to make it clear or that coloured sign " > " to ignore the point x = - 2.

You are misleading people without showing the circle clearly.

The circle I can see is clearly a closed one, therefore oops question not oops me!

I thought that the circle was closed because it looks closed to me.

Because the number is greater than negative two, and the dot is open
