x = 1
axis of symmetry of the function y = –2x² + 4x –6?
where does the parabola hit the x axis?
2 x^2 - 4 x + 6 = o
x^2 - 2 x + 3 = 0
(x-3) (x+1) = 0
x = 3 and x = -1
that is on the vertical line of symmetry and the line is halfway between
so at x = 1
Correct, x = 1 represents the axis of symmetry for the function y = –2x² + 4x – 6. The parabola will hit the x-axis at x = 3 and x = -1, with the axis of symmetry being x = 1.
