Question 702630
What do I do I need to give the x intercepts and and the coordinates of the vertex and sketch the graph 

Here's the problem y= x^2-4x-4 
---
The vertex occurs at x = -b/(2a) = 4/(2*1) = 2
---
f(2) = 2^2 - 4*2 -4 = -8
---
Vertex: (2,-8)
------
Graph: 
{{{graph(400,400,-10,10,-10,10,x^2-4x-4)}}}
