Which of the following correctly completes the square for the equation
below?
x2+4x=27

O A. (x + 4)2 = 43
O B. (x + 2) 2 2
O C. (x+ 2)2 = 43
O D. (x + 4)2 = 31

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
