What is the axis of symmetry and vertex for the graph #y=x^2-6x+4#?
The vertex is located at the point
As usual there are several methods you might choose to solve this question. One method is "completing the square". If you are not familiar with the method is may seem to be a bit strange. Here's the solution:
When a quadratic equation is written in this form it is telling me that the vertex is located at
