How do you find the axis of symmetry and vertex in intercept form

The video tutorial explains the intercept form of a quadratic equation, highlighting its usefulness in finding the zeros or roots. It details the process of determining the axis of symmetry and the vertex when a quadratic is in intercept form. The tutorial uses function notation to demonstrate how to find the vertex by plugging in the axis of symmetry into the quadratic equation.
