Answer

Final Answer: The values of \(b\) and \(c\) that make the equation \(y=14 x^{2}+b x+c\) have vertex \((-9,-9)\) are \(b=\boxed{252}\) and \(c=\boxed{1125}\).

Steps

Step 1 :We are given the vertex form of a parabola as \(y=a(x-h)^{2}+k\) where \((h,k)\) is the vertex of the parabola.

Step 2 :In this case, we know that \(a=14\), \(h=-9\), and \(k=-9\).

Step 3 :We can expand this equation to get it in the form \(y=ax^{2}+bx+c\).

Step 4 :After expanding, we get the equation as \(y=14x^{2} + 252x + 1125\).

Step 5 :By comparing coefficients, we find that \(b=252\) and \(c=1125\).

Step 6 :Final Answer: The values of \(b\) and \(c\) that make the equation \(y=14 x^{2}+b x+c\) have vertex \((-9,-9)\) are \(b=\boxed{252}\) and \(c=\boxed{1125}\).
