Answer:
2nd Box
4th Box
Explanation:
The factors of a graph is whenever the graph touches the x-axis.
A standard factor has the format (x-a), where a is the x-value.
From the graph, we can see that the graph touches the x-axis at x=3 and at x=4.
Therefore, this means that our factors are:
![(x-(4))\text{ and } (x-(3))](https://img.qammunity.org/2021/formulas/mathematics/high-school/fvhst1ipyvm1gnfc78jr3c07jgbhsmm20f.png)
Simplify:
![(x-4)\text{ or } (x-3)](https://img.qammunity.org/2021/formulas/mathematics/high-school/6cdd8khiixr9yte0hvclbz0xrry958x5or.png)
Check the second and fourth boxes.
And we're done!
