Mathematics OpenStudy (anonymous):

Which equation represents the axis of symmetry of the function y = â€“2xÂ˛ + 4x â€“6? (1 point) y = 1 x = 1 x = 3 x = â€“3 OpenStudy (anonymous):

y = â€“2xÂ˛ + 4x â€“6 = xÂ˛ - 2x +3 = (x-1)Â˛ + 4 so the vertex of the parabola is in (1,4) so answer is x= 1 OpenStudy (anonymous):

ups, made a mistake. is (x-1)Â˛ +2, but answr is the same anyway OpenStudy (callisto):

even though your answer is correct for x=1, i think there's a problem with your steps. you cannot just cannel the '-2' y = â€“2xÂ˛ + 4x â€“6 =-2( xÂ˛ - 2x) -6 = -2(x-1)Â˛ - 4 vertex should be (1, -4) and the axis of symmetry is x=1 OpenStudy (anonymous):

i got 1 for x too
