Which is the graph of f(x) = –(x + 3)(x + 1)?

On a coordinate plane, a parabola opens down. It goes through (0, negative 3), has a vertex at (2, 1), and goes through (4, negative 3).

On a coordinate plane, a parabola opens down. It goes through (negative 3, 0), has a vertex at (negative 2, 1), and goes through (negative 1, 0).

On a coordinate plane, a parabola opens up. It goes through (negative 4, 3), has a vertex at (negative 2, negative 1), and goes through (0, 3).

The second graph.

Reason: f(x)=−(x+3)(x+1) has zeros x=−3 and x=−1, opens downward (leading coefficient −1), and its vertex is at x = (−3+−1)/2 = −2 with f(−2)=1, so the parabola goes through (−3,0), (−2,1), (−1,0).
