Classifying Polynomials
Write the polynomial in standard form: -7 - 3x3+ 4x5 +2x2
4x5 - 3x3 + 2x2 -7
Find the zeros of the function: y = (x - 3)(x + 2)
-2, 3
Which special points on graphs will help you to find its zeros?
The X-intercepts
(-6x2)(5x)
-30x3
Today's objective
SWBAT determine zeros of polynomial graphs and classify them
Classify the polynomial by the number of terms (provide the name): x3 + 2
Binomial
What does zero's of a function mean?
Zero's mean that the x-values make the expression =0
Sketch a graph of a polynomial that has two zeros.
a parabola whose vertex is below the x axis
What is the fundamental theorem of algebra? Give an example and explain. Write it down
The degree of a polynomial determine the number of solutions
The house that I am in (correct spelling!)

y = (x + 1)(2x - 6)
-1 and 3
Sketch a graph of a polynomial that has five zeros.
Safontchik will determine.
(4 - x - 2x2) - (-2 + 3x - x3)

My favorite color
What is Blue
Write in standard form, then classify the polynomial by degree and number of terms (provide the names): 3x3 + 8 - x3 - 7x2
2x3 - 7x2 + 8; cubic trinomial
Find the zeros of this function:
y = x2 + 10x + 9
-9 and -1
Explain why finding a zero is the same as finding an x-intercept
Because the x-intercept is the value of x that makes the expression = 0
