Answer:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Explanation:
Given
![y = 3x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/7gqms6xkg0tfv78ymk651vt1blkk28bw1u.png)
Required
Create a table that represents this scenario
Because x represents time, x can not be negative. So, the domain of x is:
![x \geq 0](https://img.qammunity.org/2021/formulas/mathematics/high-school/uyx387ln472vfm7h14xalgcsusrbrcib1d.png)
Assume
![x = 1](https://img.qammunity.org/2021/formulas/mathematics/middle-school/9h91c1kjchcke1mwwyxiajkyxryboly84u.png)
![y = 3 * 1 = 3](https://img.qammunity.org/2021/formulas/mathematics/college/nk7idou44l0chcobs0empp782bxz62vb2l.png)
Assume x = 4
![y=3*4 = 12](https://img.qammunity.org/2021/formulas/mathematics/college/m72i17ase70otw54rwy5ckp12fru0s6brx.png)
Assume x = 6
![y=3*6 = 18](https://img.qammunity.org/2021/formulas/mathematics/college/236a7v7wsx6qtqe006u7q7ots4e6ksy0xf.png)
Hence, the table is:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
