The graph that shows a system of equations with the same end behavior for both functions is the first graph.
The end behavior is the behavior of a function as x tends to infinity or negative infinity.
So, the two functions will have the same end behavior if in both ends the graphs go to the same direction.
If yo look at the first graph, you can see that in the right side both graphs go up.
In the left side both graphs go down.
So that graph shows two functions with the same end behavior.
