The graph of the function f(x) = x2 + 8x + 12 is shown. Which statements describe the graph? Check all that apply.

The parabola opens upward because the coefficient of x² is positive, so its vertex is a minimum, not a maximum. Its axis of symmetry is x = −8 ÷ 2 = −4, and a quadratic function has a domain of all real numbers. Factoring gives x² + 8x + 12 = (x + 6)(x + 2), so the x-intercepts are (−6, 0) and (−2, 0).
