What is the end behavior of the graph? as x approaches infinity, f(x) approaches infinity. as x approaches negative infinity, f(x) approaches negative infinity. as x approaches infinity, f(x) approaches negative infinity. as x approaches negative infinity, f(x) approaches infinity. as x approaches infinity, f(x) approaches negative infinity. as x approaches negative infinity, f(x) approaches negative infinity. as x approaches infinity, f(x) approaches infinity. as x approaches negative infinity, f(x) approaches infinity.

Imagine that this curve is a roller coaster. A dot on the roller coaster would be a car for a person to sit in, so to speak. As this car moves to the right, the car ultimately moves downward. So this means that as x gets larger, y gets smaller. Put another way: as x approaches infinity, f(x) approaches negative infinity.

Similarly, we can move the other way to work our way to the left. Moving to the left has us go up this time. As x approaches negative infinity, f(x) approaches positive infinity

These two facts point to choice B as the final answer
