Determining the zeros of a function
WebMar 27, 2024 · Graphing Polynomials Using Zeros. The following procedure can be followed when graphing a polynomial function. Use the leading-term test to determine the end behavior of the graph. Find the x− intercept (s) of f (x) by setting f (x)=0 and then solving for x. Find the y−intercept of f (x) by setting y=f (0) and finding y. WebOct 6, 2024 · There is a straightforward way to determine the possible numbers of positive and negative real zeros for any polynomial function. If the polynomial is written in descending order, Descartes’ Rule of Signs tells us of a relationship between the number of sign changes in \(f(x)\) and the number of positive real zeros.
