Question

what is a polynomial function in standard form with zeroes 1, 2, -3, and -1?

Answer 1

assume you're finding zeros of a polynomial...to get 1, one factor must be x-1 because
x-1=0
x=1

now do that with the rest...

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

and expand the right side to get the standard form

Answer 2

RIGHT.... okay. Had it wrong in my notes.
