Describe the end behavior of the graph

Answer:
f(x) -----> +∞ as x----> -∞ and f(x) -----> -∞ as x----> +∞
Step-by-step explanation:
we know that
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis.
so
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 −∞ )
In this problem
f(x) -----> +∞ as x----> -∞ (as the value of x decreases the value of f(x) increases)
and f(x) -----> -∞ as x----> +∞ (as the value of x increases the value of f(x) decreases)
