Rational Function: 3rd Degree / 2nd Degree

Here's a graphing program that shows the behavior of a rational function made up of a third degree polynomial divided by a second degree polynomial. These polynomials are presented in factored form in the following function definition:


rational function


Below is a program that graphs the above function. A link to instructions is follows the program.


f(x) = m(x - a)(x - b)(x - c) / n(x - d)(x - e)
f(x) = m(x - a)(x - b)(x - c) / n(x - d)(x - e)
f(x) = c3nx3 + c2nx2 + c1nx + c0n / c2dx2 + c1dx + c0d

    x:     y:
