Cycle 1 - Lesson 7 – Rational Functions – Reciprocal of a Quadratic Function In Lesson 6, the rational functions you analyzed had linear denominators. However, rational functions can have polynomials of any degree in the numerator and denominator. In this lesson, you will analyze and graph functions such as
Because quadratics have possibly zero, one, or two x-intercepts, a parabolic shape, and a maximum or minimum point, plotting their reciprocals becomes fairly complex.
