What is a cubic polynomial function in standard form with zeros $1,-2$, and $2 ?$
(1 point)
$f(x)=x^{3}+x^{2}-3 x+4$
$f(x)=x^{3}+x^{2}-4 x-2$
$f(x)=x^{3}+x^{2}+4 x+4$
$f(x)=x^{3}-x^{2}-4 x+4$
Final Answer: The cubic polynomial function in standard form with zeros 1,-2, and 2 is \(\boxed{f(x)=x^{3}-x^{2}-4 x+4}\).
Step 1 :The standard form of a cubic polynomial function with zeros a, b, and c is \(f(x) = k(x-a)(x-b)(x-c)\), where k is a constant.
Step 2 :In this case, the zeros are 1, -2, and 2, so the function is \(f(x) = k(x-1)(x+2)(x-2)\).
Step 3 :We don't know the value of k, but since it's not specified in the question, we can assume k=1.
Step 4 :Substituting the values of a, b, and c into the equation, we get \(f(x) = (x - 1)(x + 2)(x - 2)\).
Step 5 :Expanding this equation, we get \(f(x) = x^{3}-x^{2}-4 x+4\).
Step 6 :Final Answer: The cubic polynomial function in standard form with zeros 1,-2, and 2 is \(\boxed{f(x)=x^{3}-x^{2}-4 x+4}\).
