The image of a known inverse scale function passes through points (1,3) (1) to find the relation of the inverse scale function and draw its image; (2) to find the intersection coordinates of the primary function y = 2x + 1 and the image of the inverse scale function

The image of a known inverse scale function passes through points (1,3) (1) to find the relation of the inverse scale function and draw its image; (2) to find the intersection coordinates of the primary function y = 2x + 1 and the image of the inverse scale function

(1) Y = 3 / x, the image is slightly in the first and third quadrant
(2) Let 3 / x = 2x + 1 and solve the quadratic equation
x1=-3/2,x2=1.
The intersection coordinates are (- 3 / 2, - 2) and (1,3)
It seems that the answer above is wrong. The first intersection should be (- 3 / 2, - 2)
