There are graphs of three quadratic functions in the picture. Choose the formula which corresponds to all three functions graphed in the picture.
\( y=-(x+a)^2+3 \), \( a\in(-\infty; 0] \)
\( y=-(x+a)^2+3 \), \( a\in\mathbb{R}^+ \)
\( y=-(x+3)^2+a \), \( a\in\mathbb{R}^+ \)
\( y=-(x-3)^2+a \), \( a\in\mathbb{R}^+ \)
