Answer: B) x --> -infinity, f(x) ---> +infinity
=========================================
Step-by-step explanation:
The end behavior of that given function is the same as the end behavior of y = |x|
As x goes off to either infinity, the endpoints of f(x) and y = |x| will be the same, more or less.
For y = |x|, as x heads off to either positive or negative infinity, the y value will go off to infinity. The absolute value ensures whatever input you put in, other than x = 0, is going to be positive. This rules out choices A and C. Choice D is false because y = |x| is a continuous function for any real number x.
