Question

If you help me I'll.......

Answer 1

Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading coefficient. If the function is not a polynomial, state why.

Answer 2

This is a polynomial function of degree 12 with a leading coefficient of 2.
This is not a polynomial function as the factors are not all linear.
This is not a polynomial function because the leading coefficient is negative.
This is a polynomial function of degree 12 with a leading coefficient of -2.

Answer 3

HELP MEEEEEEEE

Answer 4

ok what does the degree of a polynomial mean?

Answer 5

its the variable with the highest exponent on it.

Answer 6

hey thxs for helping me

Answer 7

It is a polynomial function

Answer 8

@manumben

Answer 9

which dou think? a or d?

Answer 10

a

Answer 11

you tell me, for the leading coefficient we would have (x)^3*(x^2)^2 * (-x^4)(2x)

Answer 12

A then!

Answer 13

whats (-1)(x^4)*2

Answer 14

2

Answer 21

Hi phi!

Answer 22

what have you figured out so far ?

Answer 23

Well I am 99% sure its A

Answer 24

I worked it all out and had some help

Answer 25

I know that it has to be the highest coefficient

Answer 26

it is definitely a polynomial
but its coefficient on the highest term is not 2

Answer 27

oh well that other person siad it was so i was going off that.

Answer 28

you can write (1-x^4) as -1 * (x^4 - 1)
and write the -1 "out front"
-1 * stuff
the stuff will be positive (because all the x's are +)
and then the -1 will make it negative.

Answer 29

ok i gotcha

Answer 30

you will always get 1*x (to some power) from all the terms except the (2x+1)
that will give you a 2
and the -1 we put out front will make it -2

Answer 31

and thats what makes the leading term -2 right?

Answer 32

yes.

Answer 33

can you answer this now ?

Answer 34

yes its D

Answer 35

WEll thxs!
