Classifying Polynomials
Write each polynomial in standard form.
Then classify it by degree and by number of terms.
-7x + 5x4 x2 - 4x + 3x3 + 2x
b(b - 3)2 (x + 1)(x - 1)(x + 2)
Comparing Models
Sometimes you can fit data more closely by using a polynomial model of degree three or greater.
Linear Model Quadratic Model Cubic Model
Determine by inspection the end behavior
of the graph of each function:
y = 3x + 2 y = 4x3
g(t) = -t2 + t f(x) = 2x + x5
g(x) = x6 y = 3x5 - 4x4
