x^2+18x+95=2

In a graph of a quadratic equation the vert4ex is the extreme point (maximum or minimum).

To write the given equation is vertex form:


y=a(x-h)^2+k

1. Write the equation in standrad form:


f(x)=ax^2+bx+c


\begin{gathered} f(x)=x^2+18x+95-2 \\ \\ f(x)=x^2+18x+93 \end{gathered}

2. Find the coordinates of the vertex (h,k):

To find the coordinate h use the next formula:


h=(-b)/(2a)
h=(-18)/(2(1))=-9

To find the coordinate k evaluate f(x) when x=h:


undefined
