Type your answers into a text box. Please number your answers. I am looking for your current understanding of the material. Answer each question, even if it is a best guess.
1. Write an equation for a polynomial with all the following features: (write 1 polynomial with all these features combined)
a. The degree is 5
b. the polynomial has 4 terms.
c. the graph of the polynomial crosses the vertical axis at y=12.
(You may want to use equation editor to help write this equation).

Lines can be used to approximate a wide variety of functions; often a function can be described using many lines.
If a stock price goes from $10 to $12 from January 1st to January 31, from $12 to $9 from February 1st to February 28th, and from $9 to $15 from March 1st to March 31th is the price change from $10 to $15 a straight line?
It is clear that in each of the three time intervals mentioned there was a complex daily variation of prices as in an electrocardiogram. But what would be a simplified solution for a first naive view of the situation? Would a simple function hold up? What is the simplest function to represent this situation? Does your naïve initial and simplified model allow you to predict the behavior of the stock in the next month?
How can I use three “pieces” of lines to describe the price movements from the beginning of January to the end of March? Show the graph for the price movement.

Operations with Polynomials Discussion:
Suppose r(x) and t(x) are two functions with the same domain, and let h(x)=r(x)+t(x).
Suppose also that each of the 3 functions r, t and h, has a maximum value in this domain (i.e. a value that is greater than or equal to all the other values of the function).
Let M = the maximum value of r(x),
N = the maximum value of t(x), and
P = the maximum value of h(x).
How might the following always be true that M+N=P?
Prove the relationship to be true, or state what relationship does exist between the numbers M+N and P. Each reply should contain at least 40 words.
