This point goes into plot of the function: P (-8, 6.25)
I also know that: C= 11/12
The unknowns are A and B.
Do I have enough data to solve this problem?

No, you have not. You only have
$\;\;\;\;\;a(-8)^2+b(-8)+\frac{11}{12}=\frac{25}{4}=6.25\Longleftrightarrow 64a-8b+\frac{11}{12}=\frac{25}{6}$
So you only have one equation but two unknowns.
