B.O.B: reflection ツ

During this week in PreCalc Functions my class started a new unit by the name of Polynomials. It sounds complicated and the word even looks complicated. Welp, at first it was for me honestly, untill Mr. Jackson gave me a better understanding of how to graph and write an equation for a Polynomial.

When looking at the graph and equation for a Polynomial you have to know all the possible characteristics of them and i didnt know that. I learned on friday why Jackon kept saying the terms bouce,straight,curve,even, and odd. So when we all got handed the paper called "Even or Odd" I asked him about how to write an equation by looking at the graph. When you look at a graph you always want to read it left to right. So if you have to arrows going up, you know the graph will be even. This means it has a even number of degrees and a positive "a" value. Then on the graph if a line goes straight through a number, it will be written like this in an eqution (x±#) if the line bounces off a number you know in the equation the x will be squared. And if you have a curve through a number you know it will be raised to the third power. If the even degree was negative, your 2 arrows would just be going down. Now if you look at a graph and the arrow starts up and ends down, its odd and its negative. This means theres an odd number of degrees and the "a" value is negative. So when you write the equation its just like using the the same stratigies for a even graph.

Anyways, on friday i finally learned how to write an equation and draw a graph for a polynomial thanks to Jackson. I feel more confident then i did like 4 days ago.
