There are two points (x1, Y1) and (X2, Y2) on the image with inverse scale function y = K + 1 of X, if x1

There are two points (x1, Y1) and (X2, Y2) on the image with inverse scale function y = K + 1 of X, if x1

X 1 is less than x 2 is less than 0, so x 1 and x 2 are all negative, Y 1 is greater than y 2, so y decreases with the increase of X, and x 1 and x 2 are all negative, so K + 1 is greater than 0, K ＞ - 1

There are two points a (x1, Y1) and B (X2, Y2) on the image with inverse scale function y = - 4 / X. when X1 > x2 > 0, what is the size relationship between Y1 and Y2?
The answer is Y1 > Y2? Why?

The answer is wrong. Do you do well in teaching reference? Often the answer will be wrong. It should be Y1

It is known that a (x1, Y1) and B (X2, Y2) are on the image with inverse scale function y = K / x, and x1

When k > 0, the function is monotonically decreasing, X 1y 2;
When k > 0, the function is monotonically increasing, x1
