hmm ok this equation has addition, integer exponents, nothing silly going on.
So it's a polynomial. more specifically its a polynomial with 3 terms
> that might make which statement true?

y=x^3 describes a cubic function
what is the leading term in your equation (leading meaning - highest power of x)

It appears that one of the terms DOES have a coefficient of 8.

Being a polynomial, it doesn't have any square roots or anything funky, so there won't be any problems over the domain of the function.

Can you figure some stuff out from that? :)
