Because x = 16, y =-1/2 and y =-8/x are equal, the point P( 16,-1/2) is on the image of this function for reference! Ask if you have seen the diagram-answer the inverse proportional function property 1. K > [increase or decrease]; 0, the image is located in the first and third quadrants respectively, and in the same quadrant, y decreases with the increase of x; When k2.k > 0, the functions are all subtraction functions on x0; K0 is increasing function. The domain is x ≠ 0; The range is y≠0. 3. Because in y=k/x(k≠0), X can't be 0 and Y can't be 0, so the image of inverse proportional function can't intersect with X axis or Y axis. 4. Take any two points P, Q and intersection P, Q in the inverse proportional function image as parallel lines of X axis and Y axis respectively, and the rectangular area enclosed with the coordinate axis is S 1, S2 is S 1=S2=|K| 5. The inverse proportional function image is both an axisymmetric figure and a centrally symmetric figure, and it has two symmetry axes Y = XY =-. 6. If the positive proportional function y=mx and the inverse proportional function y=n/x intersect at two points A and B (m the signs of m and n are the same), then the two points A and B are symmetrical about the origin. 7. Let there be an inverse proportional function y=k/x and a linear function y=mx+n on the plane. If they have a common intersection, then n 2+4k m ≥ (not less than) 0. 8. Inverse proportional function y = k/x: asymptote of X axis and Y axis. 9. The inverse proportional function is symmetric about the positive proportional functions y = x and y =-x, and symmetric about the origin center. 10. In inverse proportion, if a point m is perpendicular to X and Y respectively and intersects Q and W, the inverse proportion functions with equal values of | k |1/.k in the rectangular mwqo (with O as the origin) will coincide, and the inverse proportion functions with unequal values of k will never intersect. 12. The larger the | k |, the farther the image of the inverse proportional function is from the coordinate axis. 13. [Symmetry] The inverse proportional function image is a central symmetric figure, and the center of symmetry is the origin; The image of inverse proportional function is also an axisymmetric figure, and its symmetry axis is the bisector of the included angle between X axis and Y axis.
