Question

Write a polynomial function in standard form with zeros at –4, 4, and –2
f(x)=x^3-14x^2+64x-4
f(x)=x^3+2x^2-16x-4
f(x)=x^3-32x^2+2x-16
f(x)=x^3+2x^2-16x-32

please help!

Answer 1

If a number is a zero, then x minus that number is a factor. So that means (x-(-4)), (x-4), and (x-(-2)) are all factors of the function. Since it doesn't give you more initial information, you'll get your function by multiplying those 3 factors.
