Question

PLSS HELP!! Which polynomial could have the following graph?

a.) y = (x + 2)(x - 1)(x - 3)
b.) y = (x - 2)(x + 1)(x + 3)
c.) y = -(x + 2)(x - 1)(x - 3)
d.) y = -(x - 2)(x + 1)(x + 2)

Answer 1

b

Explanation:

Roots are: -3, -1, 2

If the root is a, factor is (x-a)

So the corresponding factors are:

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

Curve is:

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