Answer:
Explanation:
Red Graph: y = x^3 + 16x^2 + 81x + 126
Blue Graph: y = x^3 + 2x^2 - x - 2
Green Graph: y = -x^3 + 15x^2 - 74x + 120
Choose the right graph by factoring out the equations and finding the zeros
Red graph:
(x + 3)(x + 6)(x + 7) x ≠ -3, -6, -7
Blue graph:
(x + 2)(x + 1)(x - 1) x ≠ -2, -1, 1
Green graph:
(-x + 4) (x - 5) (x - 6) x ≠ 4, 5, 6
