Answer 5

Thhe definition of a polynomial might help.
Here is a casual one.

f(x) can only be a polynomial if x has a power of a NON-NEGATIVE INTEGER.

See which of the following have a negative integer and strike them out! ^^

Understood? :)

Answer 6

k12? and im thinking the last one

Answer 7

thanks so much @AkashdeepDeb and @kira12341234

Answer 8

no problem i hope you get a good grade

Answer 9

thanks haha so is the answer http://static.k12.com/bank_packages/files/media/mathml_15fe2b12c4acf998f799eeb700cebeaf2a919251_1.gif

Answer 10

yea thats it

Answer 11

Not quite.
The answer is 3/x

Reason:

That is because if f(x) = 3/x [Which it cannot be]

f(x) = 3*\(x^{-1}\)

But we know that x cannot be a negative integer and so the answer. :)

Understood? :)

Answer 12

so http://static.k12.com/bank_packages/files/media/mathml_ef35d7e6654b23fc42c924cf824478fd0d3f9d46_1.gif

Answer 13

yep.

Answer 14

cool thank you I think I get that one.

Answer 15

Answer 17

I'm thinking it's either the first or second one.

Answer 18

Here is another hint:

The power x carries cannot be a fraction either so which one do you think it is, now?

Answer 19

nope. Try again! :D

Answer 20

okay I get that now so is it -winces- the third one?

Answer 21

yep. You got that right! :D

Answer 22

\[THE DUMB BLONDE BRAIN DOESN'T FUNCTION PROPERLY\]

Answer 23

THANK THE LORD!

Answer 24

so what does this mean? : Find the degree of the polynomial.

2p2q – 3pq + q2

Answer 25

Depends on what the polynomial is actually!

The polynomial maybe f(p) or f(q)

But I'll tall you the answer both ways.

DEGREE MEANS THE HIGHEST POWER OF THE POLYNOMIAL! :D

So

\(2p^2q – 3pq + q^2\)

has the degree as 2, as it is the highest power.

Understood? :)

Answer 26

Yeah! thanks so much! i really want to understand this so maybe a couple more?
