Question

identify the variable expression that is not a polynomial:
a: x+12
b: 33
c: x^9+y^3
d: y^9+27

Answer 1

damn they all look like polynomials to me

Answer 2

@phi any ideas?

Answer 3

maybe c because it is a polynomial in two variables, but it is still a polynomial
33 is certainly a polynomial (degree 0)

Answer 4

or maybe 33 because it is not a "variable polynomial"? very idiosyncratic this problem

Answer 5

I just found a site that says
"A polynomial is a monomial or the sum or difference of monomials. Each monomial is called a term of the poynomial"

and a little later says
"Difference between a monomial and a polynomial:"

I really don't know what they are trying to teach here. btw, is 33 a "variable expression"?

Answer 6

i really don't know. i am wondering where this problem came from
a lousy text, or a not so great math teacher

Answer 7

The question is asking for a "variable expression" that is not a polynomial
if they said
sin(x)
or log(x^2)
I could answer. Here I would say 33 and make a note to the teacher that this is a goofy question.

Answer 8

well this is not a goofy question hang on

Answer 9

i got the answer i'll say it if you say im here so i know your listening

Answer 10

hey you there?

Answer 11

don't message your teacher cuz the answer is C since it has a negative exponent

Answer 12

tada its C

Answer 13

If the variable is on the denominator, it is a rational expression. Of the choices, C. x^-9 + y^3 has x in the denominator [note the negative exponent so of course its c there you have it C

Answer 14

See ya around blonde chic hahaha

Answer 15

Is there is a typo in the question?
c: x^9+y^3

If either exponent is negative, then this is not a polynomial
But as written, both exponents are positive

Answer 16

its c

Answer 17

I did all the math plus im into triganometry

Answer 18

so im good at this easy stuff

Answer 19

Jerry you are saying the question has a typo?

Answer 20

no i am not

Answer 21

phi try searching typo it is not a typo
