Answer: Choice B
As x increases, y increases
As x decreases, y increases
---------------------------------------------------------------------------
No matter what x does (increase or decrease), y is increasing. This is basically saying "go to the left or right, and the graph will move upward"
Put more technically
As x approaches positive infinity, y approaches positive infinity
As x approaches negative infinity, y approaches positive infinity
Side Note:
Some books might describe this as "rising to the left; rising to the right"
