Question

Which expression is a polynomial?

Answer 1

I would probably go with 2/x +3x

Answer 2

That function is identical to 3x+2x^(-1)

Answer 3

So b.gif?

Answer 4

thats the answer

Answer 5

no! I was wrong

Answer 6

it is d.gif

Answer 7

y

Answer 8

why is it that?

Answer 9

The answer is d for a few reasons. Polynomials must have no variables in their denominator, but but a and b both have those; therefore, a and b are not answers.

Answer 10

A polynomial must have multiple terms, in d, we have terms of x^1 and x^0

Answer 11

D is also a linear expression, which by its definition is a polynomial

Answer 12

We cancel out d because polynomials can't have roots of x; no square roots of letters allowed xD
