Answer-
End behavior for increasing x represents that the height of each bounce will approach 0.
Solution-
From the graph the exponential equation is,

From the properties of negative exponential function properties, as x increases, the value of y decreases.
So, in this case, as x or number of bounce increases, y or the height of bounce decreases. And eventually the value becomes zero.
Therefore, end behavior for increasing x represents that the height of each bounce will approach 0.
