SOLUTION: graph including any oblique asymptotes (x^2+5)/(x+1). I know how to graph it in a calculator. this problem is one found on pg 300 matched problem 6. I am not understanding how t

You can put this solution on YOUR website!
Let's do some analysis.
When you look at the function, and you're interested in asymptotes, you need to ask a couple of questions.
1. When does the denominator go to zero?
2. What happens when x gets very large in the positive direction?
3. What happens when x gets very large in the negative direction?
Let's look at each question.
1. The denominator goes to zero at x=-1.
So at x=-1, your function is undefined.
Just to the right of it, the function goes near positive infinity (x+1>0).
Just to the left of it, the function goes near negative infinity (x+1<0).
So at x=-1, you have a vertical asymptote.
2. As x gets very large positively,

So for very large x, the function looks like y=x.
As an example, at x=100,

So you have another asymptote that looks like the function y=x.
3. As x gets very large negatively,

So for very large x, the function also looks like y=x for large positive x
As an example, at x=-100,

So you have another asymptote that looks like the function y=x for large negative x.
But it all together and you can graph the function.
