Question

HELP!!! What statement describes this function. f(x) = 2x^3 + 2x^2 -x? is it not a function, many-to-one, or one to one?

Answer 1

of course it is a function

Answer 2

since you wrote
\[f(x)=\text{something}\] it had better be one

Answer 3

and it is many to one, since is increases, then decreases then increases

Answer 4

It depends on the domain.

Answer 5

good point actually. i was assuming that you use the natural domain,
\[\mathbb R\]
