Ответ:
| Дробь | x=1 | x=2 | x=4 | x=−4 | x=−1 | x=−2 |
|---|---|---|---|---|---|---|
| \(\dfrac{x}{3-x}\) | \(\frac12\) | 2 | −4 | \(-\frac47\) | \(-\frac14\) | \(-\frac25\) |
| \(\dfrac{x+1}{2x-1}\) | 2 | 1 | \(\frac57\) | \(\frac13\) | 0 | \(\frac15\) |
Например: при \(x=1\), \(\dfrac{x}{3-x}=\dfrac{1}{3-1}=\dfrac12\).
