Before solving the problems, we recollect the rules and formulae related to this topic
If F(x)=a(x-p)^2+q is the given function then
The vertex: (p, q)
Line of symmetry: x-p=0. This is got by equating the 'square term' in the given equation (in the given form)to zero.
Minimum value (only when a is positive): is ...
