利用计算器,列出自变量和函数值的对应值如下表:
| x | 0.2 | 0.6 | 1.0 | 1.4 | 1.8 | 2.2 | 2.6 | 3.0 | 3.4 | … |
| y=3x | 1.149 | 1.516 | 2.0 | 2.639 | 3.482 | 4.595 | 6.063 | 8.0 | 10.556 | … |
| y=x3 | 0.008 | 0.036 | 1.0 | 2.744 | 5.832 | 10.648 | 17.576 | 27 | 39.304 | … |
- A.(0.6,1.0)
- B.(1.0,1.4)
- C.(1.4,1.8)
- D.(1.8,2.2)
