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) option B
The answer is 2,-1 hopefully so x is 2 and you subtract it with 4x then its going to come 2 then you subtract 3 and 2 equal 2,-1 i am not really sure but yeah
