Question

Hey There Everyone! :)
I need some help. :)
Find a third-degree polynomial function such that f(0) = -24 and whose zeros are -1, 2, and -3. Using complete sentences, explain how you found it.

Answer 1

well start with the zeros

if
x = -1 is a zero then (x + 1) is a factor
x = 2 is a zero then (x -2) is a factor
x = -3 is a zero then (x + 3 is a factor

so the polynomial is

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

to find the value of a, substitute x = 0 and f(0) = 24

then evaluate

last step with be writing the polynomial in expanded form.

hope it helps
