If the image of the inverse scale function passes through point a (2,3), then are points B (- √ 2,3 √ 2), C (2 √ 3, - 3) d (9,2 / 3) on the image of the function
Let the inverse scale function be y = K / X
∵ y = K / X over a (2,3)
∴k=yx=6
Ψ B and C are not on the image of this function
D is on the image of the function
By the way, you are also a junior 3
