The graph of y=|x| looks like a letter V. You're given that the domain of the graph goes from √(5) ≤ x ≤ √(13), so treat everything else outside that domain as if they don't exist.
If you remove everything else outside of √(5) ≤ x ≤ √(13) then you're left with a graph of a line with a min at √(5) and max at √(13)
