Answer 1

your roots are -2 and 3

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

now you just have to find k, you can use your y intercept

-3 = k(2)(-3)

k = 1/2

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

expand that bad boy

y = 1/2*x^2 -1/2*x -6

Answer 2

\[y = \frac{ 1 }{ 2}x^{2}-\frac{ 1 }{2 }x - 6\]

Answer 3

you gave me the wrong picture! haha, that's why it's wrong

Answer 4

your roots for THIS one are -3 and -1

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

-3 = -3k

k = 1

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

y = -x^2 - 4x - 3
