Read allIn this video I will show you through multiple examples how to find the vertex, directrix and focus given the equation of a parabola. We will first find the vertex and then determine the value of p to find the focus and directrix. Understanding where the vertex, directrix and focus lie are very helpful graphing and determining the opening and shape of a parabola.
