Question

The black part of each graph represents the solution.

Answer 1

x≤ -2

Explanation:

we want black part, so we know it's going to be to the left of -2.

the black dot at -2 means we include -2. if it was just an unfilled dot (circle) we exclude -2 (ie it would just be ( < -2)

so answer is x≤ -2
