40.5 is the correct answer
The answer is -4/-3 or 4/3 because when you use the formula y2-y1/x2-x1 you plug in those numbers and get 4/3
First, We observe that the function is a parabola that grows
For this case, we must first graph the function to observe the behavior of the same.
We see that the vertex of the function is located at the point:
(x, y) = (- 2, -3)
The point is a minimum.
Answer:
(x, y) = (- 2, -3)
It is a minimum.
