Answer:
Ist graph:The solution is greater equal to -4.Second graph:The solution is less than 6.
Explanation:
We have given a graph.
We have to identify the solution of this graphs.
In the first graph,
The solution is greater equal to -4 the equality holds because the dot at -4 is filled it means that it is part of solution.
In the second graph:
The solution is less than 6. The equality doesnot hold because there is a hole at 6.6 is not part of solution.
