For this case, the first thing we must observe are the cut points of the parabola with the horizontal axis.
We have then:
[tex] (x, y) = (-3, 0)
(x, y) = (-1, 0)
[/tex]
Therefore, we can write the equation in its factored form as follows:
[tex] (x + 3) (x + 1) = 0
[/tex]
Rewriting we have:
[tex] x ^ 2 + x + 3x + 3
x ^ 2 + 4x + 3
[/tex]
Answer:
The equation that could be solved using the graph above is:
A. [tex] x ^ 2 + 4x + 3 = 0 [/tex]
