Quizplus · Accepted Answer

The minimum value of the function occurs at the vertex of the parabola. The vertex is located at the point with the x-coordinate equal to the axis of symmetry, which is given by x = -b/2a. In this case, the axis of symmetry is x = 2, so we need to find the y-coordinate of the point on the graph where x = 2. We can see that this point lies on the curve labeled "f(x)", and we can read off the y-coordinate from the vertical axis. The y-coordinate appears to be approximately -2.5. The only choice that matches this value is B.
