Graphing polynomials using zeros
WebThe zeros of a polynomial are the solutions to the equation p(x) = 0, where p(x) represents the polynomial. If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. WebOct 31, 2024 · How to: Given a graph of a polynomial function, identify the zeros and their mulitplicities If the graph crosses the x -axis at a zero, it is a zero with odd multiplicity. If the graph touches and bounces off of the x -axis, it is a zero with even multiplicity. The higher the multiplicity of the zero, the flatter the graph gets at the zero.
