What is a polynomial function in standard form with zeroes 1, 2, 3, and -3?
a. x^4-3x^3+7x^2-27x-18
b.x^4+3x^3-7x^2-27x-18
c. x^4-3x^3-7x^2+27x-18
d. x^4+3x^3-7x^2-27x-18

Answer 1

a polynomial function in standard form with zeroes a, b, c, and d:
f(x)=(x-a)(x-b)(x-c)(x-d)

Answer 2

in your case
a=1
b=2
c=3
d=-3

Answer 3

then as you plug in the information, expand the polynomial....

Answer 4

how do you expand?

Answer 5

f(x)=(x-1)(x-2)(x-3)(x+3)
