    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 ...

    Solution Summary

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