Answer:
D. Min (3, -4)
Step-by-step 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)

Vertex is well shown on the graph

It's at

  • (3,-4)

Look at the parabola

  • As x coordinate of vertex is positive then -b/2a is also +ve
  • Parabola is opening upwards.
  • The vertex is minimum them

Option D
