Question

The graph of f(x) = x3 + x2 - 9x - 9 is shown.

Answer 1

Answer:

-1, 3, -3

Step-by-step explanation:

I don't see the graph, but you can solve by factoring:

$x^3+x^2-9x-9=0\\x^2(x+1)-9(x+1)=0\\(x+1)(x^2-9)=0\\(x+1)(x+3)(x-3)=0$

By the factor theorem, the solutions of f(x) are -1, 3, and -3.
