Question

Is this expression a polynomial function? 3x^8-6ix^2+(pi)(times)x

Answer 1

is that an " i " on the second term? If so then it's not a polynomial function. It's an irrational function

Answer 2

Yes, that is an i, and what's an irrational function? What does it mean?

Answer 3

Sorry. I didn't mean irrational number. I meant unreal numbers. My english is kinda bad.

\[i=\sqrt{-1}\] which is impossible to solve. That's why you call him "i"

Answer 4

So that's why it isn't a polynomial function? ok! Thank you!

Answer 5

Yes. You've got the point
