Answer:

A cubic function

Explanation:

When you multiply powers of a same base, the exponents sum. So, if we multiply a function like
ax^2+bx+c with a function like
dx+e we get


(ax^2+bx+c)(dx+e) = adx^3+bdx^2+cdx+aex^2+bex+ce = adx^3+(bd+ae)x^2+(cd+be)x+ce

which is a cubic function, because it is written in the form


\alpha x^3+\beta x^3 + \gamma x + \delta
