Dec 6, 2024 · How to graph polynomial (quadratic, cubic, quartic) functions with examples. Also, learn to find the degree, end behavior, and roots of the graph.

In this lesson, we will use the above features in order to analyze and sketch graphs of polynomials. We will then use the sketch to find the polynomial's positive and negative intervals.

Aug 13, 2025 · We discuss how to determine the behavior of the graph at x-intercepts and the leading coefficient test to determine the behavior of the graph as we allow x to increase and decrease …

Nov 1, 2021 · How to: Given a graph of a polynomial function, write a formula for the function. Identify the x -intercepts of the graph to find the factors of the polynomial.

Polynomial functions of degree 2 or more have graphs that do not have sharp corners; recall that these types of graphs are called smooth curves. Polynomial functions also display graphs that have no …

To graph polynomial functions, find the zeros and their multiplicities, determine the end behavior, and ensure that the final graph has at most n – 1 turning points.

Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.
