##### Solution Summary

The vertex and intercepts for an equation are found and a graph is sketched.

##### Solution Preview

y=x^2-4x-12

Vertex:

Use formula x=-b/(2a) for x-coordinate of y=ax^2+bx+c

In our case

a=1

b=-4

c=-12

So x=4/2=2 is the x-coordinate of the vertex

y=2^2-4*2-12=-16 ...
