The graph of the function f(x) = (x + 6)(x + 2) is shown. Which statements describe the graph? Check all that apply.

The zeros are x = −6 and x = −2, so the axis of symmetry is halfway between them: x = (−6 + −2)/2 = −4. The parabola opens upward, so its vertex is a minimum, not a maximum, and the function decreases before x = −4. A polynomial is defined for every real x, and because the graph opens upward and crosses the x-axis at −6 and −2, it is negative between those roots.
