Question 806785: I have some more practice workbook questions I need help with. Graphing a parabola of the form y = (x-a)2 + c.
y=(x+2)^2-1
Can anyone explain what points need to be plotted?

You can put this solution on YOUR website!
y = x^2+4 x+3
the vertex
vertex | (-2, -1)
and when y=0
factors are
(x+1) (x+3)
x=-1 and x=-3
