The question is asking "for what values of x is this graph less than or equal to y=2. Lets look at both these graphs:
Looking at the graph, the V-shape is less than or equal to the y=2 horizontal line between x=0 and x=2. These are the answers. Lets now try to get these 2 answers through algebra:
and note the < has changed to a >
So, and
or which matches the findings from the graph
