Задание
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 \(\displaystyle y=-\frac{1}{x}{\small :}\)
\(\displaystyle \rm I\) | \(\displaystyle \rm II\) |
\(\displaystyle \rm III\) | \(\displaystyle \rm IV\) |
- \(\displaystyle {\rm I}\)
- \(\displaystyle {\rm II}\)
- \(\displaystyle {\rm III}\)
- \(\displaystyle {\rm IV}\)
