Дана функция \(\displaystyle y=-\frac{1}{x}{\small .}\) Вычислите значения функции в точках:

\(\displaystyle \small x\)\(\displaystyle \small -4\)\(\displaystyle \small -2\)\(\displaystyle \small -1{,}6\)\(\displaystyle \small -1\)\(\displaystyle \small -0{,}4\)\(\displaystyle \small -0{,}25\)
\(\displaystyle \small y=-\frac{1}{x}\)[ ][ ][ ][ ][ ][ ]
 
\(\displaystyle \small x\)\(\displaystyle \small 0{,}25\)\(\displaystyle \small 0{,}4\)\(\displaystyle \small 1\)\(\displaystyle \small 1{,}6\)\(\displaystyle \small 2\)\(\displaystyle \small 4\)
\(\displaystyle \small y=-\frac{1}{x}\)[ ][ ][ ][ ][ ][ ]

Выберите правильный график с точками, лежащими гиперболе \(\displaystyle y=-\frac{1}{x}{\small :}\)

\(\displaystyle \rm I\)\(\displaystyle \rm II\)
\(\displaystyle \rm III\)\(\displaystyle \rm IV\)
  • \(\displaystyle {\rm I}\)
  • \(\displaystyle {\rm II}\)
  • \(\displaystyle {\rm III}\)
  • \(\displaystyle {\rm IV}\)
