Ok, so this is probably really easy and I'm just not seeing it, but I'm stuck on this.
Solve problem for the specified variable:
y=a(x-h)^2+k, solve for a
so I thought I should first square x-h and then distribute a
I got y=a(x^2 -xh-xh+h^2)+k
then y=ax^2 -2axh+ah^2 +k
Now I have no idea how to isolate A. Any help?
