Given the parabola Y1 = ax Λ 2-2x + C through (0, - 1) inverse scale function y2 = K / X through (1, a), compare the size of Y1 and Y2

Given the parabola Y1 = ax Λ 2-2x + C through (0, - 1) inverse scale function y2 = K / X through (1, a), compare the size of Y1 and Y2

Substituting the point into the function, we can get Y1 = ax Λ 2-2x-1, y2 = A / X
A I don't know whether it's a positive number or a negative number. We have to discuss it according to the situation
