Given that parabola C1: y = 2x2 and parabola C2 are symmetric with respect to line y = - x, then the Quasilinear equation of C2 is () A. x=18B. x=-18C. x=12D. x=-12

Given that parabola C1: y = 2x2 and parabola C2 are symmetric with respect to line y = - x, then the Quasilinear equation of C2 is () A. x=18B. x=-18C. x=12D. x=-12

Because the Quasilinear equation of y = 2x2 is y = - 18 and the symmetric equation of y = - x is x = 18, the Quasilinear equation of parabola is x = 18, so a is selected
