f(x) = x^3 - 9x
- leading coefficient - you look at the highest power. here x^3 is the highest power so the leading coefficient is 1 because x means 1.
-zeros. you factor the equation so here you factor x out so it will be x (x^2 -9). you can factor x^2-9 so the new factoring equation will be x (x + 3) (x - 3) = 0. solve for x so the zeros will be 0, 3, -3.
-sufficient solutions will be 0, 3, -3
