The curve `y=x^2/2+x+1` is symmetric with respect to the line `x-k`, then `k= `

Statement 1 : The curve y=-(x^2)/2+x+1 is symmetric with respect to the line x=1 Statement 2 : A parabola is symmetric about its axis.

Statement I The curve y = x^2/2+x+1 is symmetric with respect to the line x = -1 . Statement II A parabola is symmetric about its axis.

Statement-1: The curve y=(-x^(2))/2+x+1 s symmetric with respect to the line x = 1. Statement -2: A parabola is symmetric about its axis.

Statement I The curve y = x^2/2+x+1 is symmetric with respect to the line x = 1 . because Statement II A parabola is symmetric about its axis.

Statement I The curve y=(x^(2))/(2)+x+1 is symmetric with respect to the line x=1 . because Statement II A parabola is symmetric about its axis.

The curve y=-(x^(2))/(2)+x+sin^(2)x+sin^(2)((5 pi)/(2)-x) is symmetric with respect to line having equation

The graph of curve x^(2)=3x-y-2 is strictly below the line y=k ,then-
