Answer:
C, y=2x(x-4)
Step-by-step explanation:
All the other equations can be graphed as lines, but C is the only one that is a parabola (a curve).

Completing the square is your method here:
(x^2 + 2x + 1) - 3 = 1 (I added a 1 on both sides so we can make that term squared
(x+1)^2 = 1 + 3
(x+1)^2 = 4
Hope this helped!
