Answer:
D. Min (3, -4)
Explanation:
This curve is a parabola, the graph of a quadratic function. It has a kind of u-ish, v-ish shape. Right there at the bottom, where the curve appears to be making a u-turn, is the vertex. That point is at (3,-4).
Also, it is a low point of the curve, which makes it a minimum of this upward opening parabola. Sometimes this curve can be flipped upside down, in which case it would have maximum.
But this one has a minimum at (3,-4)
