WebHow To: Given a graph of a polynomial function of degree n n, identify the zeros and their multiplicities. If the graph crosses the x -axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x -axis and bounces off of the axis, it is a zero with even multiplicity. If the graph crosses the x -axis at a zero ... WebJan 6, 2024 · The code works correctly.

"WebA "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2. By experience, or simply guesswork. " - Crossing zeros
