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)

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!
