Step 1
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
Step 2
Graph the function and explain the end behavior
From the plot above we can deduce the following from the end behavior;
1) As x approaches +∞, f(x) approaches -∞.
2) As x approaches -∞, f(x) approaches +∞
Hence the answer will be option A
