Unformatted text preview: 5ø 5 3 21 5 Here is the sketch for this function. Notice that this time the middle region doesn’t have the same behavior at the asymptotes as we saw in the previous example. This can and will happen fairly often. Sometimes the behavior at the two asymptotes will be the same as in the previous example and sometimes it will have the opposite behavior at each asymptote as we see in this example. Because of this we will always need to get a couple of points in these types of regions to determine just what the behavior will be. © 2007 Paul Dawkins 243 College Algebra Polynomial Functions Introduction In this chapter we are going to take a more in depth look at polynomials. We’ve already solved and graphed second degree polynomials (i.e. quadratic equations/functions) and we now want to extend things out to more general polynomials. We will take a look at finding solutions to higher degree polynomials and how to get a rough sketch for a higher degree polynomial. We will also be looking at Partial Fractions in this chapter. It doesn’t really have anything to do with graphing polynomials, but nee...
