A1. The function is given by $f(x)=-2(x+3)^{2}+2$. Which statement is correct?

(A) The function is decreasing everywhere.

(B) The vertex is at the point $T(3,2)$.

(C) The function has no real zeros.

(D) The graph is a parabola that is symmetric with respect to the line $x=-3$.

(E) None of the given statements is correct.
A1. From the function's record, we see that its graph is a parabola with the vertex $T(-3,2)$ and is symmetric with respect to the line $x=-3$.
