Graphs Of Polynomials And Rational Functions
Gbogbo ọrọ náà
A well-drawn sketch can reveal everything about a function: where it crosses the axes, where it shoots off towards infinity, and how it behaves for very large or very small values of the variable. In this topic you will learn to read and produce those sketches for polynomials of any degree and for rational functions whose denominator is linear.
You will connect the algebra you already know (roots, factors, long division) with the geometry of curves, and master the concept of asymptotes: the invisible boundary lines that a graph approaches but never crosses. These skills are tested heavily on both Papers 1 and 2 of the Edexcel 4PM1 examination.
