Help? Please Graph too! Explain in as much steps as possible how to graph it? If I try and answer my way through it, I will literally fail--I kid you not. I would really appreciate it if you'd take some time to type out the steps with the solutions. I know that's much, but please--I really need this!
Don't worry about failure with this question. We'll get you to work through it. As for the first aspect of it, the domain, what values of x are allowed in the denominator? Hint: the denominator cannot be zero, so it is good to ask what values CANNOT be allowable for x? Show work
Since the domain has an unallowable value, and you say that you know that value, see what happens as x approaches that value from the right-hand side and from the left-hand side separately. Then see what happens to the corresponding "y" value.
HERE IS THE EXAMPLE : http://www.analyzemath.com/Graphing/Graph_Abs_Val_Func.html AND HERE : THE STEPS http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/col_alg_tut31_graphfun1.htm
We will get the shape of the graph by exploring the various values of x. We will look at what happens to y as x as it goes to infinity, negative infinity, and any unallowable values of x from the right and from the left.
If you let x go to infinity, what happens to the denominator?
And after you answer that question, if you let x go to infinity, what happens to the whole expression 1 / (x + 1)? What does that go to?
