A cubic function has roots at 3,-2 and - 1. Write out the function I factored form

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

Step-by-step explanation:

given the roots are x = 3, x = - 2 and x = - 1, then the factors are

(x - 3), (x + 2) and (x + 1)

The cubic function is the the product of it's factors, hence

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