Hey guys, been a while since I've done a question like this, a bit rusty was hoping you could help me clear some things.
Identify the type of curve and sketch the graph. I know it's a parabola, but having some trouble with it. I have this so far;
y = x^2+2x
0 = x^2 +2x
0 = x(x+2)
x = 0, and -2
So the y - int is (0,0)
If I want to sketch a graph though how would I go about doing it, and how do I get the vertex without using derivatives?
