Given the image of parabola C1: y = x ^ 2-2x as shown in the figure, fold the image of C1 along the Y axis to get the image of parabola C2 Given the image of parabola C1; y = x ^ 2-2x as shown in the figure, fold the image of C1 along the Y axis to get the image of parabola C2. 1) if the line y = x + B and parabola y = ax ^ 2 + BX + C (a is not equal to 0) have and only have one intersection, the line is said to be tangent to the parabola. If the line y = x + B is tangent to parabola C1, the value of B is calculated 2) When the line y = x + B and the image C1, C2 have two intersections, the value range of B
