Best ResponseYou've already chosen the best response.1A zero of a function will have the form (xa), where a is a zero. So, to get a cubic function with those zeroes, think of how you could manipulate (xa) to get a cubic (exponent 3) function. For example, 6 is a zero of your function, so start out writing (x6).

Best ResponseYou've already chosen the best response.1Yes. You don' even have to multiply it out. It's valid as it is. But you can verify that it does give you a polynomial of degree 3. (because there is just an x, and with not power, in the three terms.. you can imagine that multiplying it out will give some kind of "x^3" term)
