What is the range of the function f(x) = −(x + 3)2 + 7? all real numbers less than or equal to 7 all real numbers greater than or equal to 7 all real numbers less than or equal to −3 all real numbers greater than or equal to −3

we have

we know that

The function is a vertical parabola open downward

The vertex is the point

The vertex is a maximum

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

That means

All real numbers less than or equal to

therefore

the answer is the option

All real numbers less than or equal to

x + 4/7
