### 7 Steps to Graph a Polynomial

by Yaneli Morales, CAPS Math Tutor 1. Find overall degree of function. Example: The overall degree of this function is 5. You get this number by adding all the exponents of the equation. In this case x has an exponent 2, the quantity (x+2) has an exponent of 2 as well, and the quantity (x-4) … More 7 Steps to Graph a Polynomial

### Graphing Rational Functions

The simplest rational function that we know is   f(x) = 1/x. Here is its graph. Knowing the shape of this basic function, we can know graph more complex rational functions by using transformations of f(x) = 1/x. For example: We are going to give you a trick that you might use when solving more … More Graphing Rational Functions

### Be Rational—Use Partial Fractions While Integrating

If you’re in some sort of calculus class, you’ve probably seen lots of different integration problems. You might even encounter some that you can’t immediately solve without some sort of manipulation. If you’re trying to integrate a tricky rational function, you can follow these steps. To illustrate the steps, we’ll look at the following example: … More Be Rational—Use Partial Fractions While Integrating
