Unformatted text preview: Math 1650 Lecture Notes Â§ 3.1 Jason Snyder, PhD Polynomial Functions and Their Graphs Page 1 of 10 Â§ 3.1: Polynomial Functions and Their Graphs Graphs of Polynomials The graphs of polynomials of degree 0 or 1 are lines and the graphs of polynomials of degree 2 are parabolas. As the degree of the polynomial increases, the graphs become more complex. The graphs of several polynomial functions are shown below: x y ? = ? x y ? = ? 2 ?Â¡ = Â¢ Â£ ? Â£ + Â¢ Â£âˆ’ 1 ? Â£âˆ’ 1 + â‹¯ + Â¢ 1 ? + Â¢ Polynomial Functions A polynomial function of degree n is a function of the form where Â£ is a nonnegative integer and Â¢ Â£ â‰ 0. The numbers Â¢ Â£ , Â¢ Â£âˆ’ 1 , â€¦ , Â¢ 1 , Â¢ are called the coefficients of the polynomial. The number Â¢ is called the constant coefficient or constant term . The number Â¢ Â£ , the coefficient of the highest power, is the leading coefficient , and Â¢ Â£ ? Â£ is called the leading term .
