Given the following quadratic function: f(x) = x ^2 - 2x - 8,
(1) Rewrite the function in vertex form. Identify the vertex.
Vertex form is: , where (h,k)=vertex.
We need to create a perfect square trinomial by adding and subtracting the same number, so you are really only adding 0.
:
f(x)=x^2-2x-8
f(x)=(x^2-2x+__)-___-8 Fill the blanks with (1/2(-2))^2=(-1)^2=1

The vertex (h,k)=(1,-9)
Happy Calculating!!!
