Hey guys what's up? I am new to this forum, so I am sorry if I posted in the wrong area..
Anyways, I have a question on Parabolas. I know how to find the Vertex, Axis of Symmetry, X,Y Int. and so on, but I am having trouble graphing it. My teacher said I need to find three good points to graph it, but I have no idea what she means. I mean I know how to graph it, but the A variable throws me off.. I'll give an example:
y=3(x-1)2-9
Vertex: (1,-9)
Axis of Symmetry: x=1
Width- Narrow
Direction- Up
X Int.= 1 plus/minus square root of 3
Y Int.= -6
Min: y=-9
How would you get three good points from this? Thank you so much to those that take the time to read and help!
