Write each polynomial function in standard form, classify it by degree, and determine the end behavior of its graph. Show all work.
a. y=12-x^4
b. y=2x^3-6x+3x^2-x^4+12
c. y=10-3x^3+3x^2+x^4

They're parts a, b, c, not answers

Answer 2

is this from a test

Answer 3

no @micahm

Answer 4

\[\large y=12-x^4\]
Write the terms in decreasing exponents for standard form :
\[\large y=-x^4+12\]

Answer 5

what point r u tring to make

Answer 6

do you know how to find degree of polynomial ?

Answer 7

Hold on I think I got it

Answer 8

-x^4+12
quartic binomial
down and down

??

Answer 9

Perfect!

Answer 10

Yay! I think I got it then! Can you check the other two real quick?

Answer 11

b. y=-x^4+2x^3+3x^2-6+12; down and down; quartic polynomial

Answer 12

Yes you got it!

Answer 13

c. y=x^4-3x^3+3x^2+10; up and up; quartic polynomial

Answer 14

Answer 15

Great! Thanks! Would you mind helping me with another?

Answer 16

wil try ask..

Answer 17

A polynomial function P(x) has degree n. If n is even, is the number of turning points of the graph of P(x) even or odd? What can you say about the number of turning points if n is odd?
