A4. The graph of a quadratic function has its vertex at point $T(2,-3)$, and it intersects the $y$-axis at point $N(0,3)$. On the parabola, there is also the point
(A) $A(4,3)$
(B) $B(4,2)$
(C) $C(3,4)$
(D) $D(3,2)$
(E) $E(2,3)$
A4. The functional expression of the quadratic function with the vertex at point $T(2,-3)$, which intersects the $y$-axis at point $N(0,3)$, is $f(x)=\frac{3}{2} x^{2}-3 x+3$. On the graph of this quadratic function, point $A(4,3)$ lies.
