What is the vertex of the graph of the function below?
y = x^2 - 8x + 12
A. (2, -4)
B. (4, -4)
C. (4, 0)
D. (2, 0)
y = x^2 - 8x + 12
A. (2, -4)
B. (4, -4)
C. (4, 0)
D. (2, 0)
The vertex of a quadratic function y = ax^2 + bx + c is given by the formula:
Vertex (h, k) = (-b/2a, f(-b/2a))
For the function y = x^2 - 8x + 12:
Therefore, the vertex is (4, -4).
The correct answer is B. (4, -4).
