Vertex Form of the Quadratic Function
Apply the following formulas to find the values of h and k, and substitute them in the vertex form of the quadratic function
, which is
.
Given:![{\underline{\sf f(x) = 2x^2 + 6x -9}} {\underline{\sf f(x) = 2x^2 + 6x -9}}](https://tex.z-dn.net/?f=%20%7B%5Cunderline%7B%5Csf%20f%28x%29%20%3D%20%202x%5E2%20%2B%206x%20-9%7D%7D%20)
Solve for h and k.
Substitute these values in the vertex form and rewrite.
