Answer:

3x^2 - 6x - 9

Step-by-step explanation:

In order to make the function have zeros at -1 and 3 it needs to factor into:      

<u>To make that:</u>

3x^2 - 6x - 9

(3x - 9)(x + 1)

<u>To check:</u>

3x - 9 + 9 / 3 = 0 + 9 / 3

x = 3

x + 1 - 1 = 0 - 1

x = -1

So, it is correct.  

Answer:  3x^2 - 6x - 9
