Answer:
The vertex formula shows us the vertex (the point at which two lines intersect), and it also shows sum what a function. In addition, showing to how that function can be graphed. For an example, the vertex formula ( f(x)=a(x-h)^2+k ), if there is a negative sign infront of a, the graph would be flipped on the x-axis. With being able to show how a graph is graphed, transformations can also be shown. I hope this helps, and have a great day
