Question 810510: The directions say: "For each function, the vertex of the function's graph is given. Find the unknown coefficients.
y=x^2+bx+c ; (-4,-7)
I've done all of my other problems, but I do not know how to start solving it or how to solve it at all. Please help. It would be greatly appreciated. :)
