For this case we have the following equation:
 y = x2-4x + 3
 Deriving we have the following equation:
 y '= 2x-4
 We equal zero and clear x:
 2x-4 = 0
 x = 4/2
 x = 2
 Substituting in the given equation we have:
 y = (2) ^ 2-4 (2) +3
 y = 4-8 + 3
 y = -1
 The vertex will be the ordered pair:
 (x, y) = (2, -1)
 Answer:
 
(x, y) = (2, -1)

1/7 - 18/7 = -17/7

Choose Answer 4:  None of these are correct.
