1.3 Equations of Polynomials

Here is the goal of this lesson: By looking at the factored form of a polynomial identify the zeros and the order of those zeros.

1. Graph the 3 functions below in desmos. Type them exactly as you see them.

    I learned:
    Orders are shown through the exponent of the bracket.
    Order 1: Passes through
    Order 2: Touches
    Order 3: Scoots

    The numbers in the brackets are the zeros e.g. y= (x-5)^2(x+3) the zeros are at positive 5 and negative 3.

    How to determine, and show what areas of the equation are positive or negative by looking at a graph.

    And overall, how to apply what I learned in 1.2 about max/min points and degrees and apply them to questions in 1.3.
