Question

he graph of the function f(x) = (x + 2)(x + 6) is shown below. On a coordinate plane, a parabola opens up. It goes through (negative 6, 0), has a vertex at (negative 4, negative 4), and goes through (negative 2, 0). Which statement about the function is true? The function is positive for all real values of x where x > –4. The function is negative for all real values of x where –6 < x < –2. The function is positive for all real values of x where x < –6 or x > –3. The function is negative for all real values of x where x < –2.

Answer 1

Explanation:

The correct statement about the function is:

The function is positive for all real values of x where x < -6 or x > -2.

We can determine this by analyzing the given information about the graph. The fact that the parabola opens upward and passes through (-6, 0) and (-2, 0) implies that it is above the x-axis in those intervals, making it positive. The vertex of the parabola is (-4, -4), which is below the x-axis, indicating that the function is negative between -6 and -2.

Therefore, the function is positive for all real values of x where x < -6 or x > -2.
