Answer:
(4, -5)
Step-by-step explanation:
completing the square:
x^2 - 8x + 11 = 0
(x-4)^2 + 11 - (-4)^2 = 0
(x-4)^2 + 11 - 16 = 0
(x-4)^2 -5 = 0
minimum point = (4, -5)
Answer:
-5
Step-by-step explanation:
Use the vertex form, y=a(x−h)2+ky=a(x-h)2+k, to determine the values of aa, hh, and kk.
a=1a=1
h=−4h=-4
k=−5
