Find the vertex and intercepts for the Quadratic function, and sketch its graph, SHOW ALL THE STEPS IN SOLVING THE PROBLEM.
y = x^2 -4x -12
Use formula x=-b/(2a) for x-coordinate of y=ax^2+bx+c
In our case
So x=4/2=2 is the x-coordinate of the vertex
The vertex and intercepts for an equation are found and a graph is sketched.
