Also, we know the vertex is (-3,-2), which is also another point on the graph.

OpenStudy (anonymous):

What are you confused about, @mjneedshelp?

OpenStudy (anonymous):

Well what is the standard form of a quadratic equation?

OpenStudy (anonymous):

@mjneedshelp, do you know?

OpenStudy (anonymous):

Yes! In this case, since it is a graph, it is y=ax2+bx+c.

OpenStudy (anonymous):

If we know 3 points: (-6,7),(-1,2), and the vertex: (-3,-2), we can plug in these values for x and y and find a, b, and c.

OpenStudy (anonymous):

So get me the 3 equations that we can solve for a, b, and c.
