Function Notations for quadratics Given $T(x) = ax^2 + bx + c$
Find $a,\,b$ and $c$ if $T(0) = -4$, $T(1) = -2$ and $T(2) = 6$
I first made $C$ for when $x = 0,\,-4$. But don't know were to go from here. 
Any help? 

Hint: $T(1) = a+b+c$, and $T(2) = 4a+2b+c$, but $c = T(0) = -4$. Can you finish it off...?
