Graphing polynomials is the fun part! We can use our knowledge about the roots of the equation, the degree (highest power), and if it’s leading term is positive or negative to sketch it really fast! This is part of the Prelim Maths Extension 1 Syllabus from the topic Functions: Polynomials. In this post, we will explore Sums and products of roots of polynomials graphing polynomials.
Here we will learn to graph a variety of polynomials and investigate the link between the root of a polynomial equation and the zero on the graph of the related polynomial function.
