SP# 2: Unit E Concept 7: Graphing Polynomials Using Zeroes with Multiplicities, Y-intercept, and End Behavior

In this student problem you will learn how to graph a fourth degree polynomial in standard form. First you need to factor out the equation. Once you have the factors you must find the zeroes or the x-intercepts. If a zeroes has a multiplicity of two then it will bounce on the point, if it has a multiplicity of one, it will go through. The coefficient in this graph has a positive coefficient and an even exponent. So the need behaviors will both be +infinity.
You need to pay careful attention to the multiplicities to graph the equation correctly. If the multiplicity is one, then the graph goes through the x-axis. However if the multiplicity is two, then the graph bounces off the x-axis. Also you need to pay attention to the leading coefficient to find the end behavior.

WPP#3 Unit E Concept 2



SP# 1: Unit E Concept 1: Graphing Quadratic Formulas


      • What is this problem about?
        This problem shows how to graph a quadratic function. It shows the directions to graph and solve the equation.
      • What does the viewer need to pay special attention to?
      • The viewer needs to pay attention to the text and the boxes in this picture. The text and boxes are in different colors so it is easy to tell where one step ends and another begins. The viewer should also pay attention to the lines that connect things.
