(algebra ii) which equation is best represented by the graph above?
a). y = (x + 3)(x + 1)(x – 1)
b). y = (x – 3)(x + 1)(x – 1)
c). y = –(x – 3)(x + 1)(x – 1)
d). y = (3 – x)(x + 1)(x – 1)
e). y = –(x – 3)(x + 1)(x + 1)

B). y = (x -3)(x +1)(x -1)

The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).

Selection B is the only choice that has these three factors.

Comment on zeros and factors

When x = a is a zero of a polynomial function, (x -a) is a factor.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

i don't see any
