5.4.3 Quiz: Graphs of Quadratic Functions
Question 8 of 10
What is the vertex of the graph of the function below?
y=X - 8x+ 12
O A. (2, -4)
B. (2,0)
O C. (4,0)
O D. (4,-4)​

Respuesta :

Answer:

D)  (4,-4)

The vertex (h,k) = (4,-4)

Step-by-step explanation:

Explanation:-

Given that the quadratic function

 y = x² - 8x +12

 y = x² - 2(4) x+ (4)²-(4)² +12

 y = (x-4)² -16 +12

y = (x-4)² -4

Comparing vertex form of the standrad parabola

y = a(x-h)²+k

The vertex (h,k) = (4,-4)
