5. what is a cubic polynomial function in standard form with zeros 1, –2, and 2? (1 point)
= x3 + x2 – 3x + 4
= x3 + x2 – 4x – 2
= x3 + x2 + 4x + 4
= x3 – x2 – 4x + 4

Option D is correct

The cubic polynomial function in standard form is :

Step-by-step explanation:

Given the zeroes of the polynomial function 1 , -2 and 2.

i.e,   x = 1 , -2 and 2  where x is the zero of the polynomial function.

we can write this as

x - 1 = 0,

x + 2 = 0 or

x - 2 = 0  

(x - 1)(x + 2)(x - 2) =0  

Using identities

then;

Multiply the first term of the first expression with second expression;

also,

Multiply the second term of the first expression with second expression;

Now, subtract and

we get;

then, we have;

Cubic function is any function of the form where a, b, c, and d are constants and a≠0

therefore, the given function is cubic function;

so, the cubic function f(x) =
