we have

$f(x)=-(x+3)^{2}+7$

we know that

The function is a vertical parabola open downward

The vertex is the point $(-3,7)$

The vertex is a maximum

The range is the interval-----------> (-∞,7]

That means

All real numbers less than or equal to $7$

therefore

<u>the answer is the option</u>

All real numbers less than or equal to $7$
